Development of a Hydrogen Starvation Detection Technology for Fuel Cell Electric Vehicles

燃料電池の水素欠乏検知技術開発

Hydrogen starvation detection is one of key technologies to prevent fuel cell degradation, and electrochemical impedance spectroscopy (EIS) is powerful tool for it. In general, EIS can measure average electrochemical state inside a stack, and measured impedance is easily affected by electrochemical reaction distribution. So, it is necessary to understand relationship between measured impedance and reaction distribution in order to detect local hydrogen starvation caused by complex transport phenomena. For this purpose, real time impedance measurement was conducted by using a short stack with segmented cell. The results suggested developed impedance system had future possibility to detect local fuel starvation.燃料電池の劣化抑制に水素欠乏検知は重要であるが，供給ガス流れに起因する水素濃度の分布がインピーダンスに影響を与えるため，インピーダンスを用いた水素欠乏の検知は難しい．本報告では，水素欠乏時の電流密度分布とインピーダンスを計測し，インピーダンスを用いた水素欠乏検知の可能性について報告する．
