There is provided a fuel cell system capable of appropriately regenerating catalyst at the cathode side or the anode side. The fuel cell system (1) includes regeneration means (21, 24, 33, 35) for controlling the gas supply amount of a fuel gas and a oxidant gas supplied to a fuel cell (2) so as to recover the lowering of activity of the catalyst of the fuel cell (2). The catalyst regeneration process at the side of the cathode (12) of the fuel cell (2) is performed by regeneration means which reduces the flow rate of the oxidant gas to less than a stationary request in the relationship with the fuel gas, thereby lowering the cell voltage of the fuel cell (2) to a predetermined voltage. The catalyst regeneration process at the side of the anode (13) is also performed by the regeneration means which reduces the flow rate of the fuel gas to less than a stationary request in the relationship with the oxidant gas. |
