A sensor in completely solid state for determining the concentration of a gas, in particular of hydrogen, is disclosed, which is essentially constituted by electrodes separated by a protonic conductor in the solid state, in which the solid-state reference electrode is constituted by a metal hydride, or a metal-alloy hydride.

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.

A solid-state sensor for determining the concentration of gases which can react with hydrogen, in particular, of oxygen, which includes a solid-state proton conductor into contact: on the one side, with a reference electrode, constituted in its turn by a metal hydride or a metal alloy, and on the other side with an electrode which catalyses the reaction of the gas to be detected, with said sensor being connected with a power feed system which supplies current or voltage impulses, and with a system which detects the value of potential after each impulse.
