摘要： PROBLEM TO BE SOLVED: To solve poor functioning due to repetitive opening/closing of a bypass valve.SOLUTION: A target stack supply flow rate is calculated on the basis of a request from a fuel cell stack; a stack request compressor supply flow rate is calculated on the basis of a stack supply flow rate and the target stack supply flow rate; the stack request compressor supply flow rate or a lower-limit flow rate determined according to an operating state of a fuel cell system, whichever is larger than the other, is set as a target compressor supply flow rate, and a compressor is controlled according to the target compressor supply flow rate; a bypass valve is controlled on the basis of the stack supply flow rate and the target stack supply flow rate; when the stack supply flow rate falls within a prescribed bypass valve restriction range which is set by referencing the target stack supply flow rate, the bypass valve is fixed, or the drive of the bypass valve is limited; and restriction of the bypass valve is removed when the stack supply flow rate becomes larger by at least a prescribed value than the lower-limit flow rate.

摘要：【課題】循環通路内の冷却水圧力が許容限界負圧まで低下することを抑制可能な技術を提供する。【解決手段】燃料電池システム100は、反応ガスの供給を受けて発電する燃料電池スタック1と、燃料電池スタックに接続される循環通路41と、循環通路41内の冷却水を循環させる循環ポンプ45と、循環通路41に水量調整弁46を介して接続されるリザーブタンク47と、を備える。コントローラ5は循環通路41内の冷却水圧力の測定手段(第1圧力センサ)56の検出値を用いて、循環ポンプ45の駆動中に循環通路41内において冷却水量が不足する状態となるか否かを予測するステップと、水不足状態になると予測された場合に、リザーブタンク47に蓄えられた冷却水を水量調整弁46を通じて循環通路41に流入させる流入処理を実行するステップとを備える。【選択図】図2
