Zusammenfassung:PROBLEM TO BE SOLVED: To suppress generation of a puddle by controlling drainage during a period in which a bus is stopping.SOLUTION: A fuel cell system mounted on a bus comprising a vehicle exterior display unit 8 for displaying a boarding and alighting sign showing that persons are getting on and off comprises: a fuel cell 1 for generating electric energy and water by using electrochemical reaction of oxidant gas and fuel gas; and a control unit 6 for suppressing, on the basis of a signal for making the vehicle exterior display unit 8 operate, drainage of water generated by the fuel cell 1 to the outside of the bus during a period in which a boarding and alighting sign is displayed on the vehicle exterior display unit 8.SELECTED DRAWING: Figure 1 【課題】バスが停車している間の排水を制御し、水たまりができることを抑制する。【解決手段】人が乗降中であることを示す乗降中サインを表示する車外表示部8を備えるバスに搭載される燃料電池システムであって、酸化剤ガスと燃料ガスとの電気化学反応により電気エネルギと水を発生させる燃料電池1と、車外表示部8を動作させる信号に基づいて、車外表示部8に乗降中サインが表示されている間、燃料電池1が発生させた水のバス外部への排出を抑制する制御部6と、を備える。【選択図】図1
