IPC: H01M8/04
Filed: 1986-05-02
Abstract: PURPOSE:To reduce damages of a cell depending on the fluctuation of pressure difference between the cell electrodes when an inert gas is fed, by reducing the inert gas feeding amount depending on the pressure difference between the fuel electrode pressure detected value signal and the air electrode pressure detected value signal. CONSTITUTION:When the pressure difference between the cell electrodes fluctuates, an inert gas feeding amount command value signal i is found from the pressure difference signal h between the air electrode pressure detected value signal b and the fuel electrode pressure detected value signal a, by an inert gas feeding amount function setting unit 9. This signal i inputs to a lower value selection circuit 10 and its output is selected as the inert gas feeding amount setting value signal d. Therefore, the signal d and the inert gas flow detected value signal e from a flow detector 3 are compared in an adjuster 6, and, depending on the flow difference signal f, the valve opening command signal g is output to an inert gas flow control valve 2 to reduce the inert gas flow. Consequently, the inert gas feeding amount to the air electrode 1b can be corrected by the pressure difference between the electrodes, and an excessive rise of the air electrode pressure can be restricted.
