Abstract
An electrically conductive, substantially fluid impermeable fuel cell separator plate comprises a substantially planar major surface for facing a fluid permeable fuel cell electrode, a fluid inlet through which a fluid may be directed to the planar major surface, a fluid outlet through which fluid may be removed from the planar major surface, and at least one discrete fluid distribution feature, such as a channel, formed in the planar major surface. Within the thickness of the plate, the fluid distribution feature is fluidly isolated from the fluid inlet and the fluid outlet, such that in a fuel cell assembly the reactant fluid must pass through the adjacent fluid permeable electrode to travel between the discrete fluid distribution feature and each of the fluid inlet and the fluid outlet.
