Abstract
A membrane electrode assembly is provided comprising 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 said ion exchange membrane, said transverse fluid channels being formed by mechanically impacting an opposed surface of the sheet to displace graphite within the sheet at predetermined locations.
