Flow distribution of both fuel and oxidant from the port to the individual cells critically control the performance of a PEMFC stack in combination. The low voltage generated in a fuel cell is compounded to usable value by stacking of cells. Under ideal conditions, a fuel cell stack performance...

In the present study, two different designs of flow field have been evaluated by electrochemical impedance spectroscopy for polymer electrolyte membrane fuel cells. Ex-situ experiments were conducted in serpentine and interdigitated flow field geometry. We have investigated the serpentine type...
