This paper reviews the properties of a new microporous, composite proton conducting gel membrane, formed by swelling with aqueous acid solutions suitable polymer matrices matrices containing a dispersed ceramic fillers. The data reported show that these membranes have a high and stable conductivity, a proton transport not critically influenced by the relative humidity level and a projected very low cost. Tests in a laboratory cells have demonstrated that the membranes are basically suitable for application in polymer electrolyte fuel cells. copyright The Electrochemical Society.

Abstract
This paper reviews the properties of a new microporous, composite proton conducting gel membrane, formed by swelling with aqueous acid solutions suitable polymer matrices matrices containing a dispersed ceramic fillers. The data reported show that these membranes have a high and stable conductivity, a proton transport not critically influenced by the relative humidity level and a projected very low cost.
