Parallel three-dimensional wavy flow field of proton exchange membrane fuel cell

The utility model relates to the technical field of proton exchange membrane fuel cell flow field structures, and discloses a parallel three-dimensional wavy flow field. The flow field structure comprises an inlet flow channel, an outlet flow channel and a plurality of branch flow channels communicated with the inlet flow channel and the outlet flow channel, the branch flow channels are arranged in parallel, and the longitudinal sections of the upper surfaces of the branch flow channels are wavy curves. According to the utility model, forced convection is introduced into the flow channel withthe three-dimensional wavy structure, and speed is generated in the direction vertical to the whole battery plane, so that more reaction gas is forced to enter the gas diffusion layer and finally reach the catalytic layer, and the utilization rate of the reaction gas is improved to a great extent. Moreover, the flow channel of the wavy structure enables more gas to enter the porous layer, liquid water gathered in the poro
