Fuel cell module, fuel cell system, fuel cell power system and vehicle

Abstract

The invention discloses a fuel cell module, a fuel cell system, a fuel cell power system and a vehicle, and solves the technical problem of low power of a current fuel cell. According to the fuel cell module provided by the invention, a scheme of integrating a plurality of electric piles is adopted, the plurality of electric piles are arranged in the direction parallel to the short edge of the bipolar plate in the electric piles, and the size of a single electric pile in the short edge direction of the bipolar plate is minimum, so that the whole fuel cell module forms a cube with similar sizes due to the arrangement mode; the situation that the arrangement of the fuel cell module on the whole vehicle is affected due to the fact that the single fuel cell module is too long is avoided, the strength of the fuel cell module of the cubic structure is high in all directions, and reliability is higher. The anodes of the membrane electrodes in the two adjacent electric piles in the fuel cell module face opposite directions, so that the arrangement of the high-voltage copper bar is facilitated, the volume of the used copper bar can be obviously shortened, the complexity of the internal structure of the whole fuel cell module is reduced, and the volume power density is favorably improved.

Description

technical field [0001] The present application belongs to the technical field of fuel cells, and in particular relates to a fuel cell module, a fuel cell system, a fuel cell power system and a vehicle. Background technique [0002] Fuel cell electric vehicles are considered to be one of the most important technical routes for the development of new energy vehicles due to their long driving range, convenient fueling, and similar performance to traditional vehicles. [0003] The stack is the place where the electrochemical reaction occurs, and it is also the core part of the fuel cell power system. It is composed of multiple single cells stacked in series. The bipolar plates and membrane electrodes are alternately stacked, and seals are embedded between the monomers. After the intake end plates and the blind end plates are pressed together, they are fastened with fasteners to form a fuel cell stack. When the stack is working, hydrogen and oxygen are introduced from the inlet ...

AI Technical Summary

Problems solved by technology

[0004] The number of monolithic batteries connected in series in a single stack is limited, because when stacking, once the number exceeds a certain number, the following problems will occur: 1) The gas distribution is uneven, resulting in the underutilization of the last few batteries; 2 ) Inconsistency of the single cells, resulting in excessive voltage deviation of the cells; 3) Uneven heat dissipation, resulting in overheating of the single cell in the middle

[0005] Therefore, the current fuel cell has the technical problem of low power
