Description
Background technology
The utility model relates to new energy field, is specifically related to a kind of compact safety-type fuel cell system.
Technical field
Fuel-cell vehicle when work, the hydrogen that acts as a fuel in vehicle boarded fuel cell with atmosphere in oxygen generation chemical reaction, thereby produce the electric energy actuating motor, and then drive vehicle; This class chemical reaction just only produces water except electric energy, thereby fuel-cell vehicle is called as " genuine environment-friendly vehicle ".In addition, the energy conversion efficiency of fuel cell is higher 2～3 times than internal combustion engine.Therefore no matter be utilization from the energy, or from the environmental protection aspect, fuel-cell vehicle all is desirable vehicle.
In recent years, fuel-cell vehicle has been obtained major progress especially.World-renowned automobile factory all moves into one after another fuel-cell vehicle such as Daimler-Chrysler, Ford, Toyota and General Motors Corporation and makes the field; Therefore the on-vehicle fuel technology has also obtained significant progress.
In view of the plurality of advantages of fuel cell with respect to internal combustion engine, engineers has been attempted fuel cells applications in the multiple vehicles as energy resource supply, but regrettably such application only succeeds at oversize vehicles such as car, big buses, and on the dillies such as fork truck, almost do not have rational scheme, its difficult point is as follows:
Vehicle-mounted fuel cell system comprises fuel cell stack system and electronic control system.Fuel cell system is in operation when needing hydrogen, in order the problem such as to guarantee safely, avoid to set off an explosion, must isolate hydrogen and electronic control system; Need also simultaneously to prevent that the hydrogen gas leakage in hydrogen feeding mechanism and the pipeline from entering the air inlet passage, cause fuel battery performance to descend, even damage.
Because the space that fuel-cell car, fuel cell big bus can have fuel cell system is more, existing fuel-cell car, fuel cell big bus all are to arrange to realize electrical isolation, hydrogen, air insulated by flexible dispersion.Be to disclose a kind of fuel-cell vehicle in the patent of 2003-104140 such as: international publication number, described fuel-cell vehicle is at the lower side space configuration fuel cell of front stall (front seat), about front stall between central tunnel (center tunnel) inside take in the part of the auxiliary member of fuel cell.Disclose a kind of vehicle frame (flame) structure in the TOHKEMY 2007-025612 communique, described chassis structure has the centre frame of pair of right and left, and its mode with the supporting central control board arranges; And at the pair of right and left bogie side frame of the overall width direction arranged outside of centre frame; Taken in fuel cell unit at central control board, the DC-DC transducer has been taken in the space of the overall width direction between centre frame and bogie side frame.Therefore for oversize vehicle, its plentiful mounting space has been avoided the problem of fuel cell miniaturization.
