摘要：
A porous graphite electrode for a fuel cell is formed by impregnation of a cellulosic filter paper by coating or impregnating with a low coke yield impregnant on the active center area and with a high coke yield impregnant on the edges, followed by curing, baking, and graphitizing the electrode to form a monolithic porous graphite electrode base with a dense low porosity area at the edges with a less dense higher porosity center working area.
