Abstract
A membrane electrode assembly is provided. More particularly, an assembly is provided which includes a pair of electrodes and an ion exchange membrane positioned between the electrodes, at least one of the electrodes being formed of a sheet of a compressed mass of expanded graphite particles having a plurality of transverse fluid channels passing through the sheet between first and second opposed surfaces of the sheet, one of opposed surfaces abutting the ion exchange membrane. The surfaces of at least some of the transverse fluid channels have glassy carbon thereon or therein.
