Abstract

The invention relates to a fuel cell bipolar plate, a fuel cell stack and a vehicle. The fuel cell bipolar plate comprises a first pole plate and a second pole plate, wherein the first pole plate is provided with a plurality of first bosses which are arranged at intervals, a first groove is formed between two adjacent first bosses, the second pole plate is provided with a plurality of second bosses which are arranged at intervals, a second groove is formed between two adjacent second bosses, spaces of the first grooves and the second bosses form gas runners for gas to flow through, the plurality of second bosses and the plurality of first bosses are consistent in number and are arranged in one-to-one correspondence, each first boss is provided with a first top wall and two second side walls, the second side walls are connected with two sides of the first top wall, correspondingly, each second boss is provided with a second top wall and two second side walls, the two second side walls are connected with two sides of the second top wall, the two second side walls are correspondingly and respectively connected with inner surfaces of the two first side walls so that the second bosses are embedded into the first bosses. The volume of the fuel cell is reduced on the premise that the performance of the fuel cell is ensured.

Description

technical field [0001] The present disclosure relates to the field of fuel cells, in particular, to a fuel cell bipolar plate, a fuel cell stack and a vehicle. Background technique [0002] Due to its energy-saving, high-efficiency, and pollution-free advantages, fuel cell power generation technology has become the main direction of new energy vehicle development and research. However, in order to meet the application requirements of limited space in passenger cars, the volume specific power of the fuel cell stack has always been very critical. Among them, the stack is formed by stacking single cells in series. Therefore, the stacking method of bipolar plates in the stack is of great importance. The effect of stack volume is also becoming more and more important. In the current existing technology, the single cell is mainly composed of a membrane electrode and a bipolar plate formed by welding a symmetrical cathode plate and an anode plate. Smaller than power. Contents o...
