The effect of pulsating pressure on the performance of a PEM fuel cell with a wavy cathode surface

In the context of attempts to improve the performance of Proton Exchange Membrane (PEM) fuel cells with a heterogeneous porous gas diffusion layer (GDL) consisting of carbon paper, we investigated whether - and to which degree - pulsating the pressure in a single waveform cathode channel affects the flow field in the channel and the...
