Thermal membrane potential was measured using various ion-exchange membranes. The results follow a theory previously proposed. Thermal membrane potential was large when the membrane has high molality of fixed charges. Characteristic properties in thermal membrane potential were not observed for perfluorinated membranes compared with that for charged membranes of hydrocarbon polymer matrix. A slight deviation from the theory was observed in the dependence of temperature coefficients of thermal membrane potential on the molality of external solution. This deviation would be due to some change in the state of hydrated ions and water in membranes with the change of swelling pressure.
