摘要：
A composite of zirconium hydrogen phosphate, HZr2 (PO4) 3 (.) nH(2)O (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 200degreesC. It was possible to prepare a composite of HZP and 5P(2)O(5)-95SiO(2) glass with porosity of 12-15%. The apparent proton conductivity of HZP/5P(2)O(5)-95SiO(2) glass composite was about 10(-4)-10(-3) S cm(-1) under 100degreesC and 10(-8)-10(-7) S cm(-1) at 200degreesC.
