A MEAhaving a proton conductive membrane is sandwiched by metal platesand they are further sandwiched by heat pressable films. An openingand an openingare formed in the heat pressable filmand the metal plate, respectively so that an electrodeis used as the sensing electrode and exposed to atmosphere to be measured. Openingsare formed in the heat pressable filmand metal plate, respectively so that an electrodeis used as the counter electrode, and water vapor is supplied to the electrode from a water pack.

Proton conductor gas sensor

A proton conductor gas sensor whose durability at high temperature is enhanced by using gel not converted to sol even at high temperature in a water reservoir. Fine particles of silica are gelled by adding water thereto and agitating the mixture under shear force. The thus obtained gel () is placed in a water reservoir of proton conductor gas sensor () and fed through steam introduction port () to MEA ().
