摘要：【課題】燃料欠乏時に劣化を伴う化学反応が生じているか否かを診断可能な燃料電池診断装置を提供する。【解決手段】燃料欠乏の判定処理にて、各セル10aのうち、負電圧となるセル10aが存在する場合に、燃料欠乏が生じていると判定する。そして、負電圧となるセル10aを診断対象セルとし、当該診断対象セルのインピーダンスとインピーダンス判定閾値とを比較により燃料欠乏時に劣化を伴う化学反応が生じているか否かを判定する。具体的には、診断対象セルのインピーダンスがインピーダンス判定閾値以下となる場合に、診断対象セルで劣化を伴わない化学反応が生じていると判定し、診断対象セルのインピーダンスがインピーダンス判定閾値より大きい場合に、診断対象セルで劣化を伴う化学反応が生じていると判定する。【選択図】図8
