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.
