Abstract

In a fuel cell system 20 mounted on a fuel cell vehicle of the invention, water separated by a gas-liquid separator 38 included in a hydrogen supply system and by a gas-liquid separator 48 included in an air supply discharge system 40 is temporarily accumulated in buffer tanks 62a through 62c, which are set inside a front fender or inside a front bumper of the vehicle. The accumulated water is released from water outlets 64b and 64c located forward and backward a front wheel of the vehicle having relatively little potential effects of vehicle wind or air flow caused by motion of the vehicle. For the purpose of reducing the potential effects of the vehicle wind on the released water, the fuel cell vehicle may have an air flow path that makes the released water flown obliquely backward the vehicle by the air flow or form an air curtain of exhaust gas or the air ahead of the released water. This arrangement effectively restricts the released water from being scattered by and swirled on the vehicle wind and thereby prevents potential troubles such that the released water is scattered on other vehicles running on the side and behind.

The exhaust system of negative electrode in the fuel cell chamber 1012 has been shown in the amplification diagrammatic sketch of bottom.Cathode exhaust from the negative electrode of fuel cells 1020 comprises by the water that electrochemical reaction produced that is used to generate electricity.Cathode exhaust flows to gas-liquid separator 1021 carrying out gas-liquid separation by pipeline 1024P, and discharges from freeing pipe 1025.The water that is separated is by discharge port 1026 and accumulate in the dashpot 1027 that is arranged in vehicle 1010 belows.The water of accumulating in dashpot 1027 is discharged to atmosphere by exhaust tube 1028.Exhaust tube 1028 is arranged on the place ahead of dashpot 1027.The bottom surface of dashpot 1027 tilts to be used for smoothly from exhaust tube 1028 discharge waters from higher rear end towards lower front end.The open end of exhaust tube 1028 height H (hereinafter being called " open end height ") overhead is set to low fully, and drain water from being rolled by windstream during vehicle 1010 travels and dispersing to prevent.
In the structure of present embodiment, not by above-mentioned exhaust system, but be recycled to feed pipe 1022 to effectively utilize the remaining hydrogen that do not consume to generate electricity from the anode waste gas of anode.Anode waste gas from anode also can be discharged from exhaust system with cathode exhaust.
Figure 40 illustrates the function of dashpot 1027.Vehicle 1010 is in halted state in Figure 40 (a).Under this state, the water of accumulating in dashpot 1027 is discharged to outside vehicle from exhaust tube 1028.When vehicle 1010 is in halted state, there is not water to be rolled by windstream and disperse.
In Figure 40 (b), vehicle 1010 is in acceleration mode.Under this state, the water of accumulating in dashpot 1027 is pressed backward by the force of inertia " A " that quickens to cause.This makes the water surface leave the joint of exhaust tube 1028, thus and the discharging of inhibition water.The possibility of dispersing that the discharging of water is suppressed to reduce institute's drain water that the windstream that produces owing to under-vehicle causes.
In Figure 40 (c), vehicle 1010 is in deceleration regime.Under this state, the water of accumulating in dashpot 1027 is pressed forward by the force of inertia " A " that is caused by deceleration.This helps from exhaust tube 1028 discharge waters.The windstream that under-vehicle produces weakens because of deceleration, thereby reduces dispersing of institute's drain water relatively.The open end height of exhaust tube 1028 is arranged to suppress the abundant low height that disperses of institute's drain water ideally under deceleration regime.
As mentioned above, in the vehicle 1010 of the 7th embodiment, being arranged on the dashpot 1027 in the exhaust system and the effect of exhaust tube 1028 is the dischargings that can suppress water under the acceleration mode effectively, helps the discharging of water under the deceleration regime.During travelling usually, vehicle often repeats to quicken and slows down not travel continuously under fixing cruising speed.Thereby, help the discharging of water under the deceleration regime and suppress this set of the discharging of water under the acceleration mode, dispersing of institute's drain water during travelling can be reduced to can not influence follow-up and near the degree of smooth-ride of vehicle.
H. the 8th embodiment
Figure 41 illustrates the structure of the exhaust system of the eighth embodiment of the present invention.The structure of the 8th embodiment has an exhaust tube 1028A who has leaf valve 1028V below dashpot 1027.The effect of leaf valve 1028V is that (punching press rampressure), that is, opens and closes in response to the pressure that stops windstream in response to the fluctuation of pressure pressure of windstream during vehicle '.
The diagram of curves of bottom illustrates the effect of leaf valve 1028V.Make windstream (speed) strengthen along with the car speed increase and disperse more tempestuously from exhaust tube 1028A drain water.When car speed surpasses prescribed level Vr, because there is the possibility of the smooth-ride that influences follow-up and near vehicle, so require to suppress dispersing of water droplet.The program of this embodiment is set at the design speed Vd that disperses that is used to suppress water droplet with the value lower slightly than prescribed level Vr.
Square increase pro rata of fluctuation of pressure pressure and car speed is shown in curve P.This curve P provides one and the corresponding fluctuation of pressure pressure P of design speed Vd d.In the structure of this embodiment, regulate the operating pressure of leaf valve 1028V, so that leaf valve 1028V opens in response to the fluctuation of pressure pressure less than value Pd, and close in response to the fluctuation of pressure pressure of the value of being not less than Pd.
In the vehicle of the 8th embodiment, this being adjusted in when car speed surpasses design speed Vd closed leaf valve 1028V fully to stop the discharging of water.This set suppresses to influence the dispersing of institute's drain water of degree of the smooth-ride of follow-up and near vehicle effectively.
In the structure of the 8th embodiment, exhaust tube 1028A is positioned at the below of dashpot 1027.Exhaust tube 1028A also can be positioned at the place ahead of dashpot 1027, as the structure of the 7th embodiment.When surpassing design speed Vd, car speed needn't close leaf valve 1028V fully.This mechanism can reduce the aperture of leaf valve 1028V continuously or by stages according to car speed.
The leaf valve 1028V of the 8th embodiment can be replaced by electromagnetic valve.This distressed structure also can comprise the control unit in order to the operation of control electromagnetic valve in addition.This control unit reduces the aperture of electromagnetic valve or closes electromagnetic valve fully when car speed surpasses design speed Vd.
Figure 42 illustrates the structure of another exhaust system of a variation.In this modified example, the bottom surface of dashpot 1027A tilts towards lower rear end from higher front end with a height L.Even this inclination makes the water of accumulating in dashpot 1027A also will leave exhaust tube 1028 under the stabilized conditions shown in Figure 42 (a), thus the discharging of inhibition water.This set has suppressed the discharging of the water during vehicle stabilization travels effectively, thereby and has reduced dispersing of institute's drain water.
When vehicle is in acceleration mode following time, force of inertia " A " is used to suppress the discharging of water, shown in Figure 42 (b).On the other hand, when vehicle is in deceleration regime following time, force of inertia " A " thus be used for pushing the water of being accumulated forward and the discharging that promotes water, shown in Figure 42 (c).Travelling of vehicle generally includes section deceleration time.Thereby during stable travelling to the inhibition of the discharging of water can be to dashpot 1027A in accumulating of water cause damage.
Figure 43 illustrates the structure of the another exhaust system of another modified example.In this modified example, the rigidity exhaust tube 1028B of front opening is installed on the dashpot 1027.In shown this example, the sectional area S0 of the front opening of exhaust tube 1028B greater than with the sectional area S1 of the joint of dashpot 1027.Exhaust tube 1028B also can form has identical sectional area S0 and the drum of S1.
In the structure of this modified example, during vehicle ' to the exhaust tube 1028B fluctuating pressure of exerting pressure.The water of accumulating in dashpot 1027A flows forward to flow out exhaust tube 1028B.The outflow of fluctuation of pressure pressure restraining water.In the structure of this modified example, the effect of fluctuation of pressure pressure has suppressed the discharging of water during running at high speed effectively.
Lower curve illustrates the influence of sectional area ratio example S0/S1 to the discharging of inhibition water.Suppose as the lower limit Vr of the car speed of discharging that need to have considered to suppress water with reference to the described content of structure of the 8th embodiment and set design speed Vd.Curve P provides the cooresponding fluctuation of pressure pressure Pa with design speed Vd.In order to suppress the discharging of water, the fluctuation of pressure pressure Pa is greater than the hydraulic pressure of the water of accumulating in baffle-box 1028, to flow out from exhaust tube 1028B.The hydraulic pressure of the water of being accumulated changes along with the water yield of accumulating in dashpot 1027 (water level), but also can set corresponding to the average water yield of accumulating under the typical drive condition.The program of this embodiment will the value higher slightly than this cooresponding hydraulic pressure be set at the design value Pd of fluctuation of pressure pressure.
The pipe internal pressure generally changes with the variation of the sectional area of pipe.For example, the sectional area ratio S0/S1 of exhaust tube 1028B is set to be not less than 1 and will increases at the fluctuation of pressure pressure of the joint of exhaust tube 1028B and greater than the fluctuation of pressure pressure at the front opening place.In this modified example, based on pressure ratio Rd (=Pd/Pa) cooresponding sectional area ratio Sd determines the shape of exhaust tube 1028B, wherein, Pd is meant the design value of fluctuation of pressure pressure, and Pa is meant the cooresponding fluctuation of pressure pressure with design speed Vd.Thus by can suppress the discharging of water effectively to the control of fluctuation of pressure pressure.
