PROBLEM TO BE SOLVED: To provide a fuel battery separator which is preferably applied to medium-temperature solid polymer fuel cells, and which is improved to achieve good gas permeability even at a medium temperature higher than conventional operating temperature while a material including a thermosetting resin and graphite is used basically.SOLUTION: The fuel battery separator comprises a raw material having an expanded graphite B, graphite C and a thermosetting resin J. The weight percentages thereof are set in ranges of 15-65 wt.% for the expanded graphite B, 15-70 wt.% for the graphite C, and 7-30 wt.% for the thermosetting resin J, respectively. |
