In addition, in the first embodiment,, be that example describes with the peripheral passage that is provided in the hydrogen gas circulating system as the drain passageway of the fluid flow of discharging from fuel cell.
The fuel cell 100 of the fuel cell system 1 in first execution mode shown in Figure 1, the structure that possesses the battery pack of being built-in with, this battery pack is to possess a plurality of MEA and the overlapping monocell that forms of dividing plate to be formed, this dividing plate is formed for supplying with to above-mentioned fuel electrodes (anode) fueling gas (hydrogen), to the oxidation utmost point (negative electrode) stream of oxidizing gas (oxygen is generally air).
Supply is connected with the air supply port 101 of this fuel cell 100 as the air supply passageway 102 of the air of oxidizing gas, discharges from the air of fuel cell 100 discharges and the air drain passageway 104 of water to be connected with air outlet 103.In addition, an end of hydrogen gas circulating system 10 is connected with the hydrogen supply port 105 of fuel cell 100, and the other end of hydrogen gas circulating system 10 is connected with hydrogen outlet 106.
Hydrogen gas circulating system 10 makes unreacted hydrogen of discharging and the unreacted hydrogen recycle that generates in the water from fuel cell 100, make it in new hydrogen supplies to fuel cell 100 once more, is discharged to the outside and will generate water.This hydrogen gas circulating system 10 has: the peripheral passage 11 that an end is connected with hydrogen outlet 106; Be connected with the other end of peripheral passage 11, will be from the peripheral passage 11 hydrogen that import and moisture from gas-liquid separator 12; As the ion exchange resin parts 20 that are provided in the Impurity removal device in the gas-liquid separator 12; Importing is from the peripheral passage 13 of the gas of gas-liquid separator 12 discharges; Be connected the downstream of peripheral passage 13, as the circulation power of hydrogen gas circulating system 10 and the circulating pump 15 of working; And one end be connected with hydrogen supply port 105, to fuel cell 100 hydrogen supplies, the hydrogen supply passageway 16 that is connected at junction of two streams A of the other end and the end of downstream side of peripheral passage 13 simultaneously.In addition, label 24 is at the valve of adjusting Hydrogen Vapor Pressure when fuel cell 100 hydrogen supplies.
Gas-liquid separator 12 especially as shown in Figure 2, has the general cylindrical shape of hollow, is formed with the gas-liquid inlet 18 that is used to import from the peripheral passage the 11 hydrogen G﹠Ws of discharging, and gas discharge outlet 19 that will isolated gas discharge gas-liquid separator 12 in.This gas-liquid separator 12 is by making fluid F (gas liquid mixture) rotation that imports from gas-liquid inlet 18 and it being separated into gas and liquid.
And, be formed with in the bottom of gas-liquid separator 12 to take in and be discharged to outside discharge outlet 17 by gas-liquid separator 12 isolated water and with it.Only be equipped with and be discharged to the outside and hydrogen be not discharged to the draining valve (figure does not show) of outside structure by gas-liquid separator 12 isolated water in this discharge outlet 17.
Ion exchange resin parts 20 have cation exchange resin and anion exchange resin, and set contiguously with the inwall of gas-liquid separator 12.Therefore, from 18 importings of gas-liquid inlet and by the gas of gas-liquid separation, will be discharged into peripheral passage 13 from gas discharge outlet 19 by ion exchange resin parts 20 backs.In addition, as the ion exchange resin of the inscape of ion exchange resin parts 20, particle shape normally, but also can use fibrous ion exchange resin.
Peripheral part on the approaching side surface 21 of the incoming fluid F of these ion exchange resin parts 20 is formed with the fluid passage 22 that disperses the dispersal device that flows into as the approaching side surface 21 that makes fluid F to ion exchange resin parts 20.This fluid passage 22, particularly as shown in Figure 3, groove (ditch) by concavity forms, the groove of this concavity is defined by the concavity portion that forms on the peripheral part on the approaching side surface 21 of ion exchange resin parts 20 with by the inwall of gas-liquid separator 12, makes to be accommodated in flow of liquid such as generation water in this fluid passage 22 all over full week of fluid passage 22.
In addition; this fluid passage 22; for example also can be formed in order protecting and to take on the resinous housing that the figure of this ion exchange resin do not show, also can define by the inwall of this housing and gas-liquid separator 12 as the ion exchange resin of the inscape of ion exchange resin parts 20.
In addition, at the middle body (axle core segment cylindraceous) of gas-liquid separator 12, be formed with the gas passage 23 of the central part that connects ion exchange resin parts 20.This gas passage 23 is connected with peripheral passage 13, makes by gas-liquid separator 12 and leads to peripheral passage 13 from the fluid F separated hydrogen.

2The O reaction.
Because this cell reaction, in fuel electrodes (anode) side, unreacted hydrogen is discharged to peripheral passage 11 with generating water via hydrogen outlet 106.
Be discharged to generation water and unreacted hydrogen in the peripheral passage 11, move to gas-liquid separator 12, be separated into gas (hydrogen) and liquid (water) at this by the power of circulating pump 15.At this moment, 11 fluid F of supplying with (gas liquid mixture) become that eddy flow (cyclone) waits turbulent flow and to ion exchange resin 20 inflows from the peripheral passage.That is to say that fluid F flows into ion exchange resin parts 20 from the direction (direction shown in the arrow D Fig. 2) different with the direction that flows into to ion exchange resin parts 20.At this moment, the major part that generates the liquid of water etc. in this fluid F is incorporated in the fluid passage 22 along the inwall of gas-liquid separator 12.Be accommodated in the full week of the flow of liquid time fluid passage 22 in this fluid passage 22, the liquid that overflows from fluid passage 22 flow into the ion exchange resin parts 20, therefore, can make aforesaid liquid flow to dispersedly ion exchange resin parts 20 all in, can make spent ion exchange resin parts 20 all efficiently.
At this, because in the past in the above-mentioned fluid F (gas liquid mixture), mainly 11 inwall (inwall of pipe arrangement) flows into liquid along the peripheral passage, so when supply to gas-liquid separator 12, owing to its weight can break away from eddy flow and falls under the influence of gravity.Though the position, whereabouts of this liquid is according to the flow velocity of eddy flow and difference, common situation is near under the gas-liquid inlet 18.This phenomenon carries out all can taking place in the piping system that all fluids flow through the gas-liquid separator of mode of gas-liquid separation except utilizing eddy flow.
But, in the first embodiment, formed fluid passage 22 as mentioned above as dispersal device, even so aforesaid liquid drop to gas-liquid inlet 18 under near, because this liquid is received in the fluid passage 22, so this liquid also can flow among ion exchange resin parts 20 all dispersedly.
Flow into the liquid of ion exchange resin parts 20, be received in the discharge outlet 17 along the inwall of gas-liquid separator 12.On the other hand, hydrogen move to by ion exchange resin parts 20 gas-liquid separator 12 below after, move to peripheral passage 13 via gas passage 23.In addition, the impurity that is contained in the aforesaid liquid is adsorbed on the ion exchange resin parts 20.
And, because ion exchange resin parts 20 are configured in the gas-liquid separator 12, that is to say, the space that utilization exists in gas-liquid separator 12 originally is as the space that sets of ion exchange resin parts 20, so can not cause fuel cell system 1 self to maximize because of setting ion exchange resin parts 20.And, also maintain required bottom line as long as be used to set the parts of ion exchange resin parts 20, can suppress the increase of cost.
In addition, in the first embodiment, to the fluid passage 22 on the peripheral part on the approaching side surface 21 by being formed on ion exchange resin parts 20, the situation that makes fluid F flow into the approaching side surface 21 of ion exchange resin parts 20 dispersedly is illustrated, but be not limited thereto, also can be separated with upstream side at interval on approaching side surface 21 and set the dispersal device that makes the fluid F dispersion flow into the approaching side surface 21 of ion exchange resin parts 20 with ion exchange resin parts 20.
For example, as dispersal device, also can be as shown in Figure 4, the upstream side of the ion exchange resin parts 20 in gas-liquid separator 12 leaves the compartment of terrain with the approaching side surface 21 of ion exchange resin parts 20 and sets the fluid importing parts 26 that offer a plurality of through holes 25.Import parts 26 by setting fluid like this, the fluid F of to gas-liquid separator 12 in, supplying with from peripheral passage 11, can by a plurality of through holes 25 and under the dispersed state from surperficial 21 inflows of the approaching side of ion exchange resin parts 20.In addition, the size of through hole 25, set quantity, equipping position etc. and can at random determine.
And, as dispersal device, can also be for example shown in Figure 5, the upstream side of the ion exchange resin parts 20 in gas-liquid separator 12 leaves the compartment of terrain with the approaching side surface 21 of ion exchange resin parts 20 and sets 11 directions that supply to the going direction changing of the fluid F in the gas-liquid separator 12 and be directed to any direction change parts 27 from the peripheral passage.Change parts 27 by direction is set like this, 11 fluid F that supply in the gas-liquid separator 12 from the peripheral passage can flow on the approaching side surface 21 from ion exchange resin parts 20 under the state that disperses.
(second execution mode)
Next, with reference to accompanying drawing the second execution mode fuel cell system of the present invention is described.
Fig. 6 is near the profile that shows gas-liquid separator in the fuel cell system that is provided in second execution mode and the ion exchange resin parts.Fig. 7 is the profile of cutting open along VII-VII line shown in Figure 6.Fig. 8 is the profile of cutting open along VIII-VIII line shown in Figure 6.Fig. 9 is the ideograph that the expression fluid flows into the state of ion exchange resin parts.
In addition, in second execution mode,, and omit its detailed description for the additional identical label of the parts identical with the parts of explanation in the first embodiment.
As Fig. 6～shown in Figure 8, the fuel cell system 1 of second execution mode and the difference of first execution mode are that dispersal device is formed by the housing 30 of taking in ion exchange resin parts 20.
And, the peripheral part on the approaching side surface 32 of housing 30 with form to the recessed a little state in outflow side, be configured make and the inwall of gas-liquid separator 12 between form the fluid passage 36 of concavity.
And,,, be radially (being on two concentric circless) from central portion to peripheral part second execution mode and be equipped with a plurality of through holes 33 alternately as Fig. 6 and shown in Figure 7 on the approaching side surface 32 of housing 30.These through holes 33 are formed, and the aperture area 33 of through hole 33 of central portion side on approaching side surface 32 that the open area ratio that is formed on the through hole 33 of peripheral part side is formed on housing 30 is big.That is to say that through hole 33 is formed, be formed on and just have less aperture area more near the central portion side.Like this, even it is longer than central portion side that the length from the approaching side to the outflow side of ion exchange resin parts 20 is the peripheral part side, also can with liquid pass through the relative flow of length replenish constant, thereby can make all of spent ion exchange resin parts 20 more expeditiously.
The surface, outflow side 34 as fluid issuing of housing 30 (just Fig. 6 is following), as Fig. 6 and shown in Figure 8, become from the gas passage 23 that tilt downwards to peripheral part, promptly along with away from gas passage 23 towards the inclined plane of gravity direction crustal inclination.The effect that play on this inclined plane is, to having flow in the fluid in the ion exchange resin parts 20 particularly liquid channeling conduct so that it to above-mentioned peripheral part side shifting, makes liquid concentrate on this part.And, on the surface, outflow side 34 of housing 30, being formed with a plurality of through holes 35, fluid is from discharging here.This through hole 35 has the aperture area littler than the aperture area of through hole 33.
And,, be formed with to deflection guidance part 37 away from the direction bending of gas passage 23 at surface, outflow side 34 and boundary member gas passage 23 of housing 30.The effect that this deflection guidance part 37 plays is that the fluid stream that guiding arrives this part makes the direction of its deflection away from gas passage 23.
In addition, be formed on the configuration and the aperture area of through hole 33 on the approaching side surface 32 of housing 30, also can determine according to the inclined plane on the surface, outflow side 34 that is formed on housing 30.In detail, determined the length from the fluid intake to the fluid issuing of ion exchange resin parts 20 by the inclined plane on the surface, outflow side 34 that is formed on housing 30, be formed on the long locational through hole 33 of this length, have bigger aperture area with regard to being formed more.Like this, the peripheral part side long in the length from the fluid intake side to fluid issuing of ion exchange resin parts 20 just flows into a large amount of fluids, gas passage 23 sides short in the length from the fluid intake side to fluid issuing just flow into a spot of fluid, therefore can with liquid pass through the flow-compensated of the relative fluid of length for constant, thereby can make more expeditiously spent ion exchange resin parts 20 all.
In be provided with the gas-liquid separator 12 that is incorporated in the ion exchange resin parts 20 in this housing 30, the same with first execution mode, 11 fluid F of supplying with (gas liquid mixture) become the turbulent flow of eddy flow (cyclone) etc. and are supplied to from the peripheral passage.At this moment, the major part that generates liquid such as water in this fluid F is incorporated in the fluid passage 36 along the inwall of gas-liquid separator 12.Be incorporated in the full week of the flow of liquid time fluid passage 36 in this fluid passage 36, the liquid that overflows from fluid passage 36 moves along the inclined plane that the approaching side surface 32 at housing 30 forms, and flows into all of ion exchange resin parts 20 by through hole 33 and with dispersity.
At this moment, as described above, because through hole 33 is staggered formation, therefore on the through hole 33 of the interior perimembranous side that is formed on housing 30, liquid also can arrive along above-mentioned inclined plane.In addition, has bigger aperture area more owing to be formed on the through hole 33 of the peripheral part side of ion exchange resin parts 20, so even the length peripheral part side from the approaching side to the outflow side of ion exchange resin parts 20 is longer than central portion side, also can with liquid to pass through length corresponding flow-compensated for constant, thereby can use the integral body of ion exchange resin parts 20 more expeditiously.
The liquid that flow in the ion exchange resin parts 20 is the same with first execution mode, gas (hydrogen) moving to by ion exchange resin parts 20 gas-liquid separator 12 below after, move to peripheral passage 13 via gas passage 23.
On the other hand, in the fluid F in flowing into ion exchange resin parts 20, the impurity that aforesaid liquid contained is adsorbed on the ion exchange resin parts 20.In addition, this liquid moves to the below of ion exchange resin parts 20 by ion exchange resin parts 20, move to the peripheral part of ion exchange resin parts 20 along the inclined plane on the surface, outflow side 34 that is formed on housing 30, and concentrated this peripheral part side that is stored in.The quality of liquid is increased, thus moving (gesture) energy of the liquid relative can be increased with gas, thus expeditiously gas-liquid is separated.And, under the effect of gravity, can more easily make this liquid further move to discharge outlet 17.
And then; aforesaid liquid is discharged from the through hole 35 on the surface, outflow side 34 that is formed on housing 30, and this moment, owing to the big granulation of peripheral drop at through hole 35; so can prevent further that this liquid is for example along with the cyclone of gas is involved in etc. situation about moving to gas passage 23 with gas.The liquid of discharging from through hole 35 moves to discharge outlet 17 by gravity from the below of gas-liquid separator 12.
And then, arrive near the fluid the gas passage 23 of ion exchange resin parts 20, be directed to direction by deflection guidance part 37, so prevent that further liquid is along with the cyclone of gas is rolled into situation in the gas passage 23 away from gas passage 23.
In addition, in second execution mode, the situation that forms fluid passage 36 between the inwall of gas-liquid separator 12 and housing 30 is illustrated, but is not limited thereto, not necessarily will form fluid passage 36.Even without forming fluid passage 36, near the liquid of peripheral part that drops to housing 30 also can move along the inclined plane on the approaching side surface 32 that is formed on housing 30, flow in the integral body of ion exchange resin parts 20 with the state that disperses by through hole 33.
In addition, be formed on the angle of inclination on inclined plane on the approaching side surface 32 of housing 30, can at random determine.
And then, in second execution mode, illustrated a plurality of through holes 33 are situation about disposing radial and staggeredly, but be not limited thereto, can determine arbitrarily through hole 33 size, the position is set, pattern is set, number etc. is set.
Moreover, in second execution mode, illustrated that the fluid issuing (surface, outflow side 34) at ion exchange resin parts 20 forms the inclined plane, and then formed a plurality of through holes 35 and deflection guidance part 37, discharge the situation of fluid from through hole 35.But, be not limited thereto, also can only form the inclined plane at the fluid issuing of ion exchange resin parts 20, the fluid issuing of ion exchange resin parts 20 is tilted, only form through hole 35, can also only set deflection guidance part 37 in addition.In addition, can also suitably make up in these several two.
And then, in the angle of inclination on the inclined plane that the fluid issuing of housing 30 forms and configuration quantity, allocation position or the size etc. of through hole 35, can at random determine.
Moreover, in second execution mode, illustrated that the fluid intake at ion exchange resin parts 20 forms the inclined plane, and be formed with the situation of a plurality of through holes 33.But be not limited thereto, the shape of the fluid intake of ion exchange resin parts 20 can be determined arbitrarily.
(the 3rd execution mode)
Next, describe with reference to the fuel cell system of accompanying drawing the 3rd execution mode of the present invention.
Figure 10 is near the profile that shows gas-liquid separator in the fuel cell system that is provided in the 3rd execution mode and the ion exchange resin parts.Figure 11 is the stereogram as the rotation wing of dispersal device that is provided in the ion exchange resin parts shown in Figure 10.
In addition, in the 3rd execution mode, the parts identical with the parts that illustrated in the first embodiment add same-sign, omit its detailed description.
As Figure 10 and shown in Figure 11, being with the first execution mode difference of the fuel cell system 1 of the 3rd execution mode constitutes dispersal device by rotation alar part spare 40.
Rotation alar part spare 40 particularly as shown in figure 11, possess rotating shaft 41 and the eight rotation wings 42 and constitute, described rotating shaft 41 is rotatably installed in the periphery that is formed at the gas passage 23 in the gas-liquid separator 12, and the described rotation wing 42 is radially from rotating shaft 41 and sets equally spacedly each other.This rotates the wing 42, with respect to the axle center O direction of rotating shaft 41, extends to approximate vertical direction (footpath direction), and is set at and surperficial 21 position contacting of the approaching side of ion exchange resin parts 20.And, can rotate by the eddy flow that is fed into the fluid F in the gas-liquid separator 12.
Be provided with this rotation alar part spare 40 in be provided with the gas-liquid separator 12 of ion exchange resin parts 20, with first execution mode similarly, 11 fluid F of supplying with (gas liquid mixture) become eddy flow turbulent flows such as (cyclone) and are supplied to from the peripheral passage.At this moment, effect backspin rotor parts 40 rotations at this eddy flow make this fluid F disperse as sprinkler, thereby can make it disperse to flow into the approaching side surface 21 of ion exchange resin parts 20 equably.
In addition, because will rotate the approaching side surface 21 of the wing 42 and ion exchange resin parts 20 disposes contiguously, so can scrape by the rotation wing 42 and sweep the fluid (particularly liquid) that drops on this approaching side surface 21, it is disperseed to approaching side surface 21 more equably.
Flow into the liquid of ion exchange resin parts 20, with first execution mode similarly, inwall along gas-liquid separator 12 is received to discharge outlet 17, hydrogen move to by ion exchange resin parts 20 gas-liquid separator 12 below after, move to peripheral passage 13 via gas passage 23.And the impurity that contains in the aforesaid liquid is adsorbed on the ion exchange resin parts 20.
In addition, in the 3rd execution mode, situation about being formed with to the rotation wing 42 that extends with the direction (footpath direction) of the axle center O direction approximate vertical of rotating shaft 41 is illustrated.But be not limited thereto, also can for example as shown in figure 12 the rotation wing 42 be formed obliquely with predetermined angular α with respect to the axle center O direction of rotating shaft 41.Like this, be formed obliquely,, fluid F dispersed as releasing with sprinkler even the revolving force of rotation alar part spare 40 diminishes by making the rotation wing 42.
In addition, as other execution mode, as shown in figure 13, the rotation wing 42 also can form along with the distance of distance rotating shaft 41 to the slowly crooked structure of rotating shaft 41 directions.Perhaps, as shown in figure 14, the rotation wing 42 also can become the structure that bends to the rotating shaft direction in the position of distance rotating shaft 41 regulations.Like this, liquid is also dispersed to the interior side direction of rotation alar part spare 40.The rotation wing 42 with these structures also can make its axle center O direction with respect to rotating shaft 41 tilt with the angle [alpha] of stipulating as shown in figure 12.
In addition, as other execution mode, as shown in figure 15, the rotation wing 42 also can have the structure of the inclination (gradient) that is recessed into to outer circumferential side from rotating shaft 41 with being formed with rotating shaft 41 side direction outflow side concavities.In this case, preferably form the inclined plane that rotates the inclination complementation of the wing 42 with this on the approaching side surface 21 of ion exchange resin parts 20.Like this, the easier direction to rotating shaft 41 of liquid that drops to the outer circumferential side of rotation alar part spare 40 moves, and then can make liquid be distributed to approaching side surface 21 more equably.The rotation wing 42 with this structure also can be as shown in figure 12 with respect to the axle center O direction inclination predetermined angular α of rotating shaft 41.
And then, as other execution mode as shown in figure 16, can the porous member 46 be formed with a plurality of through holes 45 be set in the downstream (in the present embodiment at downside) of the rotation wing 42.Like this, the particularly liquid that can receive in the fluid F by the space (chamber) 47 that forms by the rotation wing 42 and porous member 46.Therefore, can after temporarily in this space 47, keeping liquid, make liquid arrive the approaching side surface 21 of ion exchange resin parts 20 from the through hole 45 of porous member 46.So, can make liquid disperse to flow into approaching side surface 21 more equably.
In addition, can be that the center is and sets a plurality of through holes 45 that are formed on the porous member 46 radial and staggeredly with rotating shaft 41.Like this, liquid can be disperseed to flow into more equably the approaching side surface 21 of ion exchange resin parts 20.
Moreover porous member 46 also can have the structure of the inclination (gradient) that has been recessed into to outer circumferential side from rotating shaft 41 as shown in figure 17 with having formed rotating shaft 41 side direction outflow side concavities.Like this, drop to the liquid of porous member 46 and can be more easily move, can further make liquid be distributed to approaching side surface 21 more equably to the direction of rotating shaft 41.In this case, also preferably on the inclined plane of the approaching side surface of ion exchange resin parts 20 21 formation with the inclination complementation of porous member 46.
In addition, in the 3rd execution mode, illustrated with approaching side surface 21 state of contact the situation of rotating alar part spare 40 rotatably is set with ion exchange resin parts 20.But be not limited thereto, rotation alar part spare 40 also can be configured in the upstream side that is separated with the interval with the approaching side surface 21 of ion exchange resin parts 20.
Moreover, the size of the rotation wing 42, configuration sheet number, the angle of inclination (α) of the rotation wing 42 etc. can at random be determined.
In addition, illustrated dispersal device in first execution mode～the 3rd execution mode, the gas-liquid separator 12 of the mode (cyclone mode) that not only may be used on utilizing eddy flow that gas-liquid is separated for example obviously can also be applied to the gas-liquid separator except utilizing the mode that eddy flow separates gas-liquid that gas-liquid is separated by pressure differential, temperature difference etc.
(the 4th execution mode)
Next, with reference to the fuel cell system of description of drawings the 4th execution mode of the present invention.
Figure 18 is near the stereogram that shows gas-liquid separator that sets in the fuel cell system of the 4th execution mode and the ion exchange resin parts, is to see the figure that internally shows.
Figure 19 is the profile of cutting open along XIX-XIX line shown in Figure 180, is the ideograph that the expression fluid flows into the state of ion exchange resin parts.
In addition, in the 4th execution mode, the additional same-sign of the parts identical with the parts of explanation is in the first embodiment omitted its detailed description.
