Abstract
A composite of zirconium hydrogen phosphate, HZr2(PO4)3·nH2O (HZP), and proton conducting glass was investigated as an inorganic solid-state proton conductor for a direct methanol fuel cell (DMFC) working at higher temperatures around 200°C. It was possible to prepare a composite of HZP and 5P2O5-95SiO2 glass with porosity of 12-15%. The apparent proton conductivity of HZP/5P2O5-95SiO2 glass composite was about 10-4-10-3 S cm-1 under 100°C and 10-8-10-7 S cm-1 at 200°C.
