Description

technical field [0001] The invention belongs to the technical field of fuel cells, and in particular relates to a simulation test device for stack cathodes of an air supply system of a fuel cell. Background technique [0002] Fuel cells generate electricity directly through the electrochemical reaction of fuel (such as hydrogen). Because fuel cells have a series of excellent performances such as high efficiency, zero emissions, stable operation, and no noise, they are regarded as the most likely power source for future automobiles. Fuel cell vehicles are the development trend of the future automobile industry. Fuel cells use electrochemical reactions to convert chemical energy into electrical energy, and are not limited by the Carnot cycle. The theoretical efficiency can reach up to 80%. Due to the influence of activation polarization, ohmic polarization and the diffusion effect of strong tea inside the battery during the chemical reaction, the power generation efficiency i...
