Summary:To provide a fuel cell power generation system in which corrosion of a cathode during startup can be suppressed.SOLUTION: A fuel cell power generation system comprises a system control device that controls the supply of anode gas to an anode and the supply of cathode gas to a cathode. The system control device can perform a first cathode gas supply mode in which low oxygen concentration gas is supplied to the cathode from a low oxygen concentration gas supply path, and a second cathode gas supply mode in which the low oxygen concentration gas supply path is cut off and air is supplied to the cathode from an air supply path. The system control device performs the first cathode gas supply mode and then switches the mode to the second cathode gas supply mode when there is a start command from a user.SELECTED DRAWING: Figure 1 【課題】起動の際のカソードの腐食を抑制可能な燃料電池発電システムを提供する。【解決手段】燃料電池発電システムは、アノードへのアノードガスの供給及びカソードへのカソードガスの供給を制御するシステム制御装置を備える。システム制御装置は、低酸素濃度ガス供給路から低酸素濃度ガスをカソードに供給する第1カソードガス供給モードと、低酸素濃度ガス供給路を遮断し空気供給路から空気をカソードに供給する第2カソードガス供給モードとを実行可能である。システム制御装置は、ユーザからの起動指令があった場合に、第1カソードガス供給モードを実行し、その後、第2カソードガス供給モードに切り替える。【選択図】図1
