Abstract
A technology for preventing degradation of a hydrogen permeable metal layer in a fuel cellis provided. A fuel cell systemincluding a fuel cellwith an anode which has the hydrogen permeable metal layer comprises a fuel cell controllerfor controlling the operation status of the fuel cell system, a temperature parameter acquisition section for acquiring a temperature parameter of the hydrogen permeable metal layer, and a hydrogen permeable metal layer degradation prevention section which reduces the hydrogen partial pressure in an anode channelfor supplying fuel gas to the anode. If a temperature of the hydrogen permeable metal layer represented by the temperature parameter deviates from a specified temperature range, the fuel cell controllercause the hydrogen permeable metal layer degradation prevention section to operate for preventing degradation of the hydrogen permeable metal layer.
