Multi-angle study of the effects of different wave flow field plates on fuel cell performance

The flow field plate is an important component of the fuel cell, and makes the flow state of the reactant gas produce obvious changes. In this paper, the method of computational fluid dynamics was used to study the influence of the waveform channel on the internal parameters of the fuel cell. Through analysis, the optimal cathode flow field waveform at different temperatures was determined. It was found that the waveform flow field plate is very limited in improving the average current density. The existence of the waveform would obviously change the distribution of liquid water. This paper has contributed to the full commercialization of fuel cells.
