Abstract

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.

保持するまでに時間がかかるなどの欠点があった。Since the conventional flow rate/pressure control device is configured as described above, when the fuel flow rate and oxidizer flow rate are changed when changing the battery output load, the battery casing (1), which was held at a constant value, The pressure difference between the battery housing (1), the fuel chamber (3), and the oxidizer chamber (4) suddenly fluctuates significantly. There is also a risk of destroying the electrolyte-impregnated porous material (matrix) and the electrodes that separate the fuel chamber (3) and the oxidizer chamber (4) between them. Another disadvantage is that it takes time to maintain the differential pressure at a constant value again after changing the flow rate.

It is an object of the present invention to provide a flow rate/pressure control device that can reduce fluctuations in differential pressure due to changes in flow rate by adding a non-interference regulator configured by a device or the like.
