Fabrication and Evaluation of Proton-conductive Composites Available at Intermediate Temperature

Abstract

Proton-conductive composites which can be utilized at intermediate temperature were fabricated using layer-structured aluminum phosphate hydrate and silicophosphate gel. The electrical conductivity of the obtained composites increased with an increase in temperature and reached an maximum value at around 110°C followed by decrease probably due to loss water. It is likely that the samples tend to recover the water leading to increase in conductivity on cooling.
