Abstract
Organic-inorganic proton electrolytes were investigated by the cross-linking of various organic monomers (PDMS, PTMO) and metal (Zr, Ti) alkoxides. Proton conductors of 12-phosphotungstic (PWA) and phosphoric acids interacted with inorganic phase of organic-inorganic hybrids. Some hybrids showed high mechanical and thermal stability up to 300°C. Moreover, high proton conducting hybrids were investigated a cell performance using single MEA cell. The organic-inorganic conducting hybrids, which have high proton conductivity and thermal stability, can be expected for applications in intermediate temperature PEFCs.
