Abstract
A graphite article useful in producing a membrane electrode assembly comprising a pair of electrodes and an ion exchange membrane positioned between the electrodes is presented. At least one of the electrodes is 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 when used in a membrane electrode assembly. At least some of the fluid channels are interconnected to enable flow of fluid therebetween.
