FUEL CELL SYSTEM AND METHOD FOR DRIVING SAME

摘要

A controller (15) conducts a termination operation in which the generation of an electric power by a fuel cell (3) is terminated, and subsequently conducts an activity recovery operation in which the supply of a fuel gas to be supplied to an anode (2a) by means of a fuel gas supply unit (10) is terminated, an inert gas is supplied to the anode (2a) by means of an anode inert gas supply unit (13), and an oxidizing agent gas is supplied to the cathode (2b) by means of an oxidizing gas supply unit (11). In this manner, the controller (15) can control so that the fuel gas supply unit (10) can re-start the supply of the fuel gas to the anode (2a) and the fuel cell (3) can re-start the generation of an electric power after the battery voltage of the fuel cell (3) which is detected by a voltage detector (14) is decreased to a first voltage or lower.
