Abstract
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 ().
