✦ Synopsis
A variety of proton conducting borosiloxane solid electrolytes containing -SO 3 H groups as proton sources were prepared. The presence of boron as a Lewis acid in the inorganic-organic hybrid structure was thought to lead to enhanced -SO 3 H dissociation, while the incorporation of alkyl groups overcame the tendency of the materials towards deliquescence at high temperatures and high relative humidity.
Robust films, prepared from composites of borosiloxane electrolyte and Nafion 117, were thermally stable and exhibited superior proton conducting characteristics to Nafion 117.
