PURPOSE:To assure safety operation of fuel cell by installing a pressure transmission unit having an air chamber and a hydrogen chamber between which is separated in airtightness by a flexible partition in each inlet of hydrogen gas and an air of a fuel cell. CONSTITUTION:An anode chamber 12 and a cathode chamber 13 are partitioned by a platinum catalyst film 14, and hydrogen gas is supplied to the anode chamber 12 and air to the cathode chamber 13, and nitrogen gas to the outside of these chambers, then a fuel cell is operated. A pressure transmission unit 60 which is separated into an air chamber 60A and a hydrogen gas chamber 60H by a diaphragm 80 and each of inlet and outlet pipes 70-3 is connected to each of associated piepes is arranged in inlets of hydrogen gas and air. When either pressure of hydrogen and air supplied to the cell 2 is varied, pressure of other gas is automaticlly followed. Therefore, large variation in pressure difference is quickly suppressed and operation is stabilized. |
