PURPOSE:To decrease variation of differential pressure caused by variation of flow rate by adding a non-interacting controller comprising a multiplier, an integrator, and an adder to output of a flow rate controller when flew rates of fuel and oxidizing agent are changed. CONSTITUTION:Deviation between inactive gas flow rate and fuel flow rate is calculated with a subtracter 18a, and the output to a flow rate control valve 8a is calculated with a flow rate controller 11a and inputted to a non-interacting controller 19. The output of oxidizing agent flow rate is calculated and inputted to the non-interacting controller 19. The output to a pressure control valve 14 is calculated by pressure of a cell chamber 1 and inputted to the non-interacting controller 19. The output to a differential pressure control valve 12a is calculated by differential pressure between a fuel chamber and the cell chamber 1 and inputted to the non-interacting controller 19. The output to a differential pressure control valve 12b is calculated by differential pressure between an oxidizing agent chamber 4 and the cell chamber 1 and inputted to the non-interacting controller 19. Output valves inputted to the non-interacting controller 19 from the controllers 11a, 11b, 16a, 16b, and 17 are calculated with the non- interacting controller 19 so as to negate interacting elements and inputted to control valves 8a, 8b, 12a, 12b, and 14. |
