Abstract
A fuel cell is fitted with a current collector situated between a ribbed separator and an electrode. The current collector is comprised of a plurality of flat wires which span the peaks of the ribs of the separator. The flat wires are of sufficient thickness, width, and frequency to support the electrode against the compressive load of the fuel cell stack. The width and frequency are alterable to suppress or enhance reactant access to the electrode.
