Abstract

　環境の温度変化に伴うアノード側の残余電流の変化を考慮した上で、腐食に伴って金属内部へ侵入する水素量を正確に計測することができる測定装置を提供することを課題とする。　金属材料からなる被検体の一方の面を腐食環境に暴露し腐食反応により発生する水素の侵入面、他方の面を水素検出面とするとき、該水素検出面側に、複数のセル群で構成された電気化学セルを設け、該セル群の個々のセルの内部にpHが９～13の電解質水溶液を充填すると共に、それぞれ独立した参照電極と対極を設置し、該セル群のうち少なくとも一つのセルを残余電流を補正するための基準セルとし、該基準セルの水素検出領域に対応する水素侵入面側の領域に、腐食環境との接触を遮断するための保護膜を設け、該基準セル以外のセルで検出したアノード電流値を、該基準セルで検出した残余電流値により補正し、この補正したアノード電流値に基づいて腐食面側からの侵入水素量を算出する。
