Description
cncN2 = cncN2 tmp * prsH2 fc b / prsH2 fc a
という式、つまり、水素加圧前のアノード窒素濃度(cncN2 tmp)と水素加圧後のアノード圧力(prsH2 fc b)とを乗じ、これを水素加圧後のアノード圧力(prsH2 fc a)で除した値として求めることができる。これにより、アノードパージ処理による窒素濃度減算を行い(ステップ14)、これによって一連の処理を終了する(ステップ15)。あとは、このようにして得られたアノード窒素濃度の推定結果(あるいは算出結果)に基づいて燃料電池スタック20の出力制限を適切に行うこととなり、これによれば、アノードの不純物濃度が高い状態での過度な発電を抑制することが可能となる。
