Summary The change of the geometry of the flow field plate will affect the distribution of reaction gas and further change the reaction rate inside the cell. This article uses computational fluid dynamics as a research method to observe the improvement of fuel cell performance of different channel geometries. In the single‐channel simulation, channel of different shapes has very limited influence on current density, but it will change the water saturation, especially near the outlet of the channel. In this research, the performance of a variable waveform flow field plate is relatively better. This will be conducive to the promotion and application of proton‐exchange membrane fuel cells in real life.
