PURPOSE:To absorb pressure variation by flow rate change and facilitate pressure control by installing gas reservoirs in exhausting paths of a fuel gas and an oxidizing gas and setting valves which are linking to pressure detectors in previous portions of each reservoir and a fuel cell. CONSTITUTION:When a load is varied, varied load is detected with a load variation detector 10 and controlled with a load variation controller 8 which controlling amounts corresponding to load variation are programmed previously to adjust flow rate adjusting valves 11 and 12. Generally, unbalance of pressure occurs by this control, but in this fuel cell system, quick unbalance of pressure is reduced because reservoirs 13 and 14 are installed in outlets of the fuel cell 1. Pressure difference caused from flow rate variation by control of flow rate adjusting valves 11 and 12 is set by operating a pressure adjusting valve 16 with pressure setting equipment 15 with standard pressure set at fuel outlet gas pressure. |
