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.
Claims8
A solid-state sensor device for determining the concentration of a gas which can react with hydrogen and consisting essentially of:
- (a) a protonic conductor having first and second sides;
- (b) a first reference electrode in contact with said protonic conductor on the first side thereof, said reference electrode being a metal hydride or metal alloy hydride which provides a constant reference potential;
- and
- (c) a second sensor electrode in contact with said protonic conductor on the second side thereof, said sensor electrode being a composite of (i) a material which catalyzes the reaction of the gas to be determined with hydrogen and, in contact therewith, (ii) a metal hydride or a metal alloy hydride.
