Abstract

Protonic conductivities of phosphate glasses made by a condensation-polymerization below liquidus temperature were Measured. Phosphate glasses of both the Sr-Ba-Pb and Sr-Zr-Pb series possess a conductivity of 6×10^-4 S/cm at 373 K, three order of magnitude as high as that of glasses made by a conventional melt-quenching. The performance of power generation was evaluated with a use of the glasses as electrolyte of fuel cells. Power density of l mW/cm² was obtained aτ 413K and 0.035atm of water partial pressure. These fuel cells were found to be operative at higher temperature and lower humidity than those of polymer electrolyte fuel cells
