Abstract
Description
まず、図1を参照して、各実施形態に係る燃料電池システム100の構成について説明する。図1は、各実施形態に係る燃料電池システム100の構成図である。図1に示すように、この燃料電池システム100は、燃料電池1と、エア供給経路10と、コンプレッサ11と、エア供給弁12と、エア排出弁13と、流量計14と、エア排出経路20と、調圧弁21と、水素供給経路30と、水素タンク31と、インジェクタ32と、圧力センサ33と、水素循環経路40と、循環ポンプ41と、水素排出経路50と、排気弁51と、制御部60と、電圧センサ70と、を備える。また、燃料電池システム100は、DC/DCコンバータ110と、PCU120と、負荷130と、を備える。
H2→2H++2e− ・・・(1)
(1/2)O2+2H++2e−→H2O ・・・(2)
H2+(1/2)O2→H2O ・・・(3)
第2の実施形態は、第1の実施形態において、低負荷運転中にカソードガスの供給量が判定閾値以上となることが複数回検知された場合にクロスリーク異常を判定する。
燃料電池システム100の運転を停止させる際には、アノードガスの供給が停止され、排気弁51が閉じられる。この運転停止時にアノードガス圧力に基づいてクロスリーク異常を判定する方法が知られている。この方法によれば、アノードガスの圧力の低下はクロスリーク量と直接的な相関があり、アノードガス圧力に基づいて正確なクロスリーク量が得られるため、クロスリーク異常が生じているか否かが定量的に判断可能である。しかし、この方法では、排気弁51等が故障している場合など、アノードガスの経路に漏れが生じているとクロスリーク異常が誤検出される。
