ABSTRACT:
A catalyst support material useful in a membrane electrode assembly is presented. The support catalyst material is elongate electrically anisotropic particles of flexible graphite, and the membrane electrode assembly includes a pair of electrodes, an ion exchange membrane having opposed surfaces positioned between the electrodes and a catalyst material on the inventive support, at least a portion of an opposed surface of the ion exchange membrane being adjacent the catalyst which is supported on the elongate electrically anisotropic particles of flexible graphite sheet.
