Performance of a membrane humidifier for a proton exchange membrane fuel cell
The liquid water produced by an electrochemical reaction at the cathode of a proton exchange membrane fuel cell blocks the pores in the gas diffusion layer, resulting in “water flooding.” At the same time, membrane dehydration leads to serious ohmic ...
