To provide a technology capable of suppressing deterioration and damage of a fuel cell due to air withering at a cathode electrode without lowering the responsiveness of a forward/backward switching operation in which a propulsion direction of the hull switches between forward and reverse in a ship fuel cell system.SOLUTION: A ship fuel cell system includes a forward/backward switching operation detection unit 51A that detects a forward/backward switching operation in which a propulsion direction of a hull switches between forward and reverse, and a load rapid increase determination unit 52 that determines whether the load is in a rapid increase state in which a rapid increase in the power generation load of a fuel cell 10 is predicted on the basis of the detection result of the forward/backward switching detection unit 51A, and an oxidant gas supply control unit 11A sets the target oxidant gas supply amount when the load rapid increase determination unit 52 determines that the load is in the rapid increase state to be larger than when the load rapid increase determination unit determines that the load is not in the rapid increase state.SELECTED DRAWING: Figure 3
【課題】船舶用燃料電池システムにおいて、船体の推進方向が前進と後進との間で切り替わる前後進切替操作の応答性を低下させることなく、カソード電極での空気枯れに起因する燃料電池の性能低下や損傷を抑制できる技術を提供する。【解決手段】船体の推進方向が前進と後進との間で切り替わる前後進切替操作を検知する前後進切替操作検知部51Aと、前後進切替検知部51Aの検知結果に基づいて燃料電池10の発電負荷の急増が予測される負荷急増状態であるか否かを判定する負荷急増判定部52と、を備え、酸化剤ガス供給制御部11Aが、負荷急増判定部52で負荷急増状態であると判定したときの目標酸化剤ガス供給量を、負荷急増判定部で負荷急増状態でないと判定したときよりも大きく設定する。【選択図】図3
