The invention relates to a self-breathing gel mobile phase special-shaped fuel cell. The fuel cell comprises an ethanol cavity, an anode layer, a gel mobile phase layer, a cathode layer and a shell which are sequentially arranged from inside to outside, wherein the ethanol cavity is cylindrical, an upper bottom surface and a lower bottom surface of the ethanol cavity are sealed, uniformly distributed through holes are formed in a side wall of the ethanol cavity, the side wall of the ethanol cavity is attached to the anode layer, the shell is cylindrical, through holes which are evenly distributed and cooling fins which are evenly distributed are arranged on the side wall of the shell, the lower bottom surface of the ethanol cavity and the lower bottom surface of the shell are coplanar, andthe ethanol cavity is lower than the shell. The fuel cell is advantaged inthat a permeation problem of ethanol on the proton exchange film is avoided through a gel mobile phase, self-breathing air suction and heat dissipation of the cell are realized through the shell, and the performance of the fuel cell is improved.

The utility model relates to a vehicle and fuel cell, fuel cell encapsulate shell thereof, fuel cell encapsulation shell include the casing, and the casing has the casing movable part that can perhapskeep away from the pile for the pile motion with the contact. When fuel cell need dispel the heat only need through adjustment casing movable part in order shrinking this casing, this moment the casing movable part with the pile contact, thereby the purpose that reaches the heat dissipation cooling is taken from the casing in out of to the heating panel of excess heat on by the casing, lower or need to reduce when using under the radiating condition at ambient temperature as fuel cell, thereby only need increase the interval between big shell and the fuel cell through adjustment casing movable part in order to spread out this casing to thereby reduce the effect that heat -conduction and reflected radiation's heat reaches heats preservation, reduces calorific loss, solved prior art and can't compromise and solve fuel cell and encapsulate the shell and can well dispel the heat and heat retaining problem when low temperature when high temperature.

The utility model relates to an on -vehicle absorption type refrigerating device and car, including cold junction connection cell's heat exchange device, still including being used for cryogenic absorption type refrigerating device, heat exchange device's hot junction with absorption type refrigerating device links to each other for provide the heat for absorption type refrigerating device. The utility model discloses the waste heat that utilizes new energy automobile's power battery provides the heat source for absorption type refrigerating device, and the realization utilizes generating heatfor freezing of power battery, can be used for the air conditioner in car main cabin in summer, on -vehicle refrigerator, and need cooling or microthermal environment on other vehicles. The utility model discloses effectively reduce new energy automobile's refrigeration energy consumption, at the recycle who has realized the energy for power battery the radiating while of cooling, practiced thrift the continuation of the journey mileage that the energy had promoted the vehicle.

On -vehicle absorption type refrigerating device and car

The utility model relates to a fuel cell system, fuel cell stack and polar plate subassembly, fuel cell stack includes the membrane electrode and locates the first polar plate and the bipolar plate ofmembrane electrode both sides, first polar plate, all be equipped with the air seal piece that is used for preventing gaseous outer hourglass and interior cluster between bipolar plate and the membrane electrode, air seal piece between first polar plate and the membrane electrode is the face seal piece, the face seal piece has the plane sealed face that forms the face seal with the correspondingside of membrane electrode, air seal piece between bipolar plate and the membrane electrode is for locating the some tree lace sealing member on the corresponding side of bipolar plate, point tree lace sealing member have with it is plane sealed to should and forming the sealed end of linear sealing with the corresponding side of membrane electrode. Compare with two sides are sealed, sealing areareduces, and local pressure grow has strengthened sealed effect, compare with two side lines are sealed, increased with the adaptation width of the sealed face of arc, can not lead to seal failure even take place the dislocation between two air seal pieces yet.

The utility model relates to an utilize on -vehicle air conditioner of fuel cell waste heat, including condenser, compressor, condenser, compressor pass through refrigerant piping and constitute circulation path, still include a fuel cell radiator, the fuel cell radiator leads to the coolant liquid pipeline to be connected with fuel cell, and the fuel cell radiator is installed in the air circulation system of on -vehicle air conditioner the inclusive AND condenser and is integrateed and be in the same place. The utility model discloses an utilize fuel cell used heat in winter, the air circulation system of air conditioner blows over radiator surface with the air, takes away the heat of fuel cell coolant liquid, if not enough through the air temperature of single heat, the condenser that can also pass through the air conditioner again carries out secondary heating, and the hot -air advanced the secondary heating after -blow and enters the passenger cabin, realized passenger cabin heating in winter, had solved present on -vehicle air conditioner and had not utilized vehicle fuel cell waste heat to warm oneself, led to the fact the problem of putting in order the car energy consumption that strengthens.

Utilize on -vehicle air conditioner of fuel cell waste heat

The invention relates to a fuel cell hybrid power system operation control method. No matter whether a vehicle is in an operation state or a stop state, namely no matter what state the vehicle is in,a fuel cell is controlled to be started, in other words, the fuel cell outputs current, namely the power is output no matter what state the vehicle is in, and the output current of the fuel cell is larger than the output current of the fuel cell in the vehicle idle speed state. Therefore, the fuel cell is controlled to output the current larger than the current corresponding to the idle speed state, the fuel cell can be prevented from being in the idle speed state, the idle speed state of the fuel cell can be cancelled through the control method, the situations of the high potential, the reduction of the membrane water content, membrane perforation, proton exchange capacity reduction, catalyst activity reduction and the like caused by the idle speed are avoided, and therefore the service life of the fuel cell is effectively prolonged.
