Abstract

A stable and conductive composite material based on NH₄PO₃ and amorphous oxides (SiO₂-P₂O₅) has been prepared by a wet-chemical route following with firing in ammonia. The composite showed high proton conductivity in both ambient air and humidified 5% H₂/Ar. A total conductivity of 6.0-19 mS/cm in the temperature range of 150-250 °C has been achieved. The conductivity (about 19 mS/cm) is stable in humidified 5% H₂/Ar during ageing at 175 °C for over 100 h. This material is a potential electrolyte for intermediate temperature fuel cells and other electrochemical devices. © 2010.
