The present invention includes a gas-permeable, hydrophilic, graphite fuel cell electrode for use in conjunction with an ionomer membrane. The fuel cell electrode includes a roughened, interstitial graphite surface enclosing micropores, upon which is deposited a catalyst for contacting an ionomer membrane. The graphite electrode has a thickness of about 40 microns.

[ What is claimed is:] [6.] A hydrophilic, graphite electrode-membrane assembly, wherein the membrane is adhered to a catalyzed graphite surface of the electrode, comprising:a fuel side electrode having a thickness that is about 40 microns, comprising: a main body made of graphite having a density about one-half that of pure graphite, the main body including a surface having micropores and mesopores and a roughened interstitial surface, wherein a catalyst is deposited on the roughened surface to form the catalyzed graphite surface;an oxidant side electrode having a thickness that is about 40 microns, comprising: a main body made of graphite having a density about one-half that of pure graphite, the main body including a surface having micropores and mesopores and a roughened interstitial surface, wherein a catalyst is deposited on the roughened surface to form the catalyzed graphite surface; and an ionomer membrane, contact the fuel side electrode and the oxidant side electrode at the roughened surface of each electrode.
