Abstract
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.
