Abstract

A gas handling technique of the gas controllable H₂ | H⁺electrolyte | Pt cell has been reported in order to obtain the reproducible gas environmental condition. The small amount of dissolved hydrogen and oxygen gas in the electrolyte has been evaluated by measurements of the temperature dependence of electromotive force (EMF) of the cell. The gas controllable technique and the evaluation method of a dilute H and O gas dissolved in an electrolyte should contribute to clarify the interfacial phenomena on electrode materials.
