✦ Synopsis

This report concerns a composite proton electrolyte suitable for use in electrochromic devices. The electrolyte consists of nanosize pyrochlore antimonic acid particles suspended in a poly(vinyl acetate) matrix by a gel route. It was found possible to substitute the antimonic acid by inert oxides of aluminum and silicon, thus making the electrolyte less harmful to the oxide electrodes of the electrochromic devices without considerably decreasing the conductivity. The proton conductivity of 24 the antimonic acid electrolyte was | 10 S / cm at room temperature, practically independent of its amount of absorbed water.

A new low temperature fuel cell based on phosphotungstic acid electrolyte was realized. The electrochemical activity was investigated by polarization curves and lifetime experiments. An output electrical power of 700mW cm-' was obtained at 25Β°C and 1 atm. Lifetime tests showed that the cell performa
