Abstract

A fuel cell having a novel configuration including a segmented gas diffusion medium (GDM) or a non-segmented GDM and a separator plate, in which the reactant flow field and liquid coolant field are integrated into one side of a single plate element. The separator plate, in one embodiment, allows for the hydration of the polymer electrolyte membrane of the fuel cell.
