Abstract

In this paper, a new proton-conductive compound of (NH₄)₂SnP₄O₁₃ was synthesized by a simple solid state method. X-ray diffraction, scanning electronic microscopy and thermal gravimetric analysis investigation were performed on this compound. The conductivity of (NH₄)₂SnP₄O₁₃ was measured by impendence spectroscopy with the temperature range of 125-275 °C under different atmospheres. Maximum conductivities of 13.8 mS cm^-1 at 275 °C under dry H₂ and 35.5 mS cm^-1 at 225 °C under wet H₂ respectively were obtained.
