Undeclared symbol 154 is blast pipes among the figure.
Below in conjunction with accompanying drawing the course of work of the present invention is described:
After control part (not shown) was assigned enabled instruction, the petrolift 123 of starting fluid supply department 120 was carried liquid fuel, and this fuel is fed to the fuel electrodes 113 of fuel cell pack portion 110 from fuel tank 121 by fuel recycle pipe 122.At this moment, fuel trim valve door the 124, the 125th, Be Controlled portion suitably opens the strength of fluid that utilizes the circulation of concentration sensor D Sustainable Control when liquid fuel is circulated smoothly, when concentration value tells the user to answer refuelling case 121 by display part (not shown) when standard value is following.
Meanwhile starting air compressor 131 carries the air in the atmosphere to supply air by air supply pipe 132 to the air pole 114 of fuel cell pack portion 110.This air becomes the steam state to be fed to air pole 114 by air adjustment valve door 135 through humidifier 141 humidifications in the middle of being, forms electric energy.
Be described in more detail as follows, open air supply portion 130 when liquid fuel is fed to the fuel channel supply of the separator 115,116 that is formed on fuel cell pack portion 110 by fuel recycle pipe 122, make air be fed to the air duct of fuel cell pack portion 110 separators 115,116 by air supply pipe 132.
At this moment, the supply valve 145 of fetching boiling water starts water pump 144, and the water of water tank 142 is fed to humidifier 141 by water supply pipe 143, and these humidifier 141 hollow cyclostrophics change the steam state into and are fed to fuel cell pack portion 110.
Fuel gas channel to separator 115,116 is to contact with air pole 114 with fuel electrodes 113 separately with air duct supplied fuel gas and air, and this moment is by electrochemical reaction generation electric energy and heat energy.
That is, fuel electrodes 113 sides take place from the electrochemical oxidation reactions of the H+ of supply of fuel:
H→2H++2e-
Conduct the ion that oxidation/reduction reaction causes in the dielectric film 112, the electrochemical reducting reaction of air supplied (oxygen) take place in the air pole 114:
4H++O 2+4e-→2H 2O
Electric power has taken place between above-mentioned fuel electrodes 113 and air pole 114, this plays electric power is the two ends of the fuel cell pack portion 110 by 111 stacks of a plurality of cells current-collector 117,118 outputs that are provided with, and the electric current of output is fed to load from current-collector 117,118.
Discharge to gas-liquid separator 152 by water-circulating pipe 151 by the water that mixes in the fuel cell pack portion 110 air pole air, wherein air is directly discharged by blast pipe 154, when water conversion valve 153 is closed water tank 142 and is opened gas-liquid separator 152 simultaneously, to humidifier 141 circulation-supplied water.At this moment, judge the water yield that is stored in the gas-liquid separator 152 by the level sensor L that is arranged in the gas-liquid separator 152, if its water yield is when being able to replace water tank 142 degree, and the water Be Controlled portion in the gas-liquid separator 152 connects conveying separately in humidifier 141.
After this, close fuel trim valve door 124,125 backs when needing refuelling case 121 and water tank 142 fuel tank 121 is replaced by another fresh fuel case 121, when fuel tank 121 and water tank 142 fuse as shown in Figure 5, do not need refuelling case 121 and water tank 142 respectively, but disposable replacing.
So, do not need yet fuel supplying smoothly of reformer, thereby avoided the volume of the system that causes with reformer to increase and the expense increase.
And, because charge and discharge liquid fuel with dismountable fuel tank, thus not only easy to carry, also reduced the danger when using.
For the water of humidifying air except the last water that uses water system, can also replace with dismountable water tank that is easy to carry, particularly be one with water tank and fuel tank, water tank is also changed together when the refuelling case, can be more convenient in the use.
Especially use the water humidifying air of from the air pole of fuel cell pack portion, discharging preheating, when particularly using heated humidifier, can use a spot of heat and obtain good humidification effect, more effective use energy with air.
