ABSTRACT:
A solid-state sensor device for determining the concentration of gases which can react with hydrogen, in particular oxygen, is disclosed, which is essentially composed of a solid-state protonic conductor put into contact, at one of its sides, with a reference electrode and, at its other side, with a composite electrode (sensor electrode), constituted by a catalytic material into contact with a hydride of a metal or of a metal alloy.
