Title: Characterization and electrochemical properties of P{sub 2}O{sub 5}-ZrO{sub 2}-SiO{sub 2} glasses as proton conducting electrolyte

Abstract

The H{sub 2}/O{sub 2} fuel cell based on the proton conducting P{sub 2}O{sub 5}-ZrO{sub 2}-SiO{sub 2} glasses was prepared by sol-gel technique. Structural characterization were carried out using X-ray diffraction spectroscopy (XRD), Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance ({sup 31}P MAS NMR), N{sub 2} adsorption-desorption analysis, differential thermal analysis (DTA) and thermal gravimetric analysis (TGA) and impedance measurements. The absorption bonds of Si-O-Si, Si-O-P and Si-O-Zr were observed in the P{sub 2}O{sub 5}-ZrO{sub 2}-SiO{sub 2} glasses which were heat treated at 600 deg. C. A sample (5P{sub 2}O{sub 5}-4ZrO{sub 2}-91SiO{sub 2}, mol%) was selected as the electrolyte for the H{sub 2}/O{sub 2} fuel cell test and yielded the maximum power density value of 8.5 mW/cm{sup 2} using electrochemical measurements at 30 deg. C under relative humidity atmosphere.
