Cathode flow velocity and pressure gradient oscillations in impedance spectroscopy of PEM fuel cells
In electrochemical impedance spectroscopy experiments with PEM fuel cells, the applied AC current induces oscillations of the mass flow across the gas diffusion layer/cathode channel interface. These oscillations perturb the air flow velocity and pressure in the cathode channel. By analogy with Berm...
