Problems solved by technology

[0002] Compared with traditional fuel vehicles, fuel cell vehicles have the advantages of environmental protection, green, etc., and basically achieve zero emissions. However, when fuel cell vehicles are currently working, hydrogen flows on the flow channel of the bipolar plate (the flow channel is usually Serpentine distribution of only a few millimeters wide and deep groove), there is a significant pressure difference between the inlet and outlet, due to problems such as reaction time, simply increasing the air supply can not significantly increase the power generation, therefore, when the vehicle is speeding up or During the deceleration process, there is a certain lag, the response is not timely, and the driving experience is reduced

Description

technical field [0001] The invention belongs to the field of new energy, and in particular relates to a fuel cell vehicle generating power test platform and a working method. Background technique [0002] Compared with traditional fuel vehicles, fuel cell vehicles have the advantages of environmental protection, green, etc., and basically achieve zero emissions. However, when fuel cell vehicles are currently working, hydrogen flows on the flow channel of the bipolar plate (the flow channel is usually Serpentine distribution of only a few millimeters wide and deep groove), there is a significant pressure difference between the inlet and outlet, due to problems such as reaction time, simply increasing the air supply can not significantly increase the power generation, therefore, when the vehicle is speeding up or During the deceleration process, there is a certain lag, and the response is not timely, which reduces the driving experience. [0003] Therefore, it is necessary to...
