PURPOSE:To provide a stable electrical output by computing and controlling incremental opening of respective regulating valves for a primary fuel, a cathode air, and a steam from the deviation between the initial cell voltage and the present cell voltage corresponding to the present output power value. CONSTITUTION:The present power value is computed from a cell output voltage and a cell output current, the corresponding initial cell voltage is computed in a function generator FG4, the deviation between the initial cell voltage and the present cell voltage is input into function generators FG'1, FD'2, and FG'3. The generators FG'1, FG'2, and FG'3 compute the valve opening increment, namely flow increment, corresponding to voltage deviations of a primary fuel regulating valve 9, a cathode air regulating valve 10, and a steam regulating valve 11, and are subsequently added to respective regulating valves to control them. Whereby, the deterioration in battery cell characteristics can automatically be detected and increase the quantity of hydrogen being supplied to a hydrogen electrode in the cell main body so as to stably provide an electrical output. |
