Inert gas such as nitrogen is fed into the cell casing 1, fuel chamber 3, oxidizing agent chamber 4 through a system 7 to set the pressure in the cell casing 1 to the required operating level. Under this state, the pressure in said casing 1, fuel chamber 3 and oxidizing agent chamber 4 will be same thereby the differential pressure meters 14a, 14b will point at zero. Then the differential pressure regulating valves 13a, 13b are opened while the flow regulating valves 11a, 11b are opened and said gate into the fuel chamber 3 and oxidizing agent valves 15a, 15b are closed to feed the required amount of fuel oxidizing agent chamber 4 to produce power.
