摘要
In this paper, a new proton-conductive compound of (NH4)(2)SnP4O13 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)(2)SnP4O13 was measured by impendence spectroscopy with the temperature range of 125-275 degrees C under different atmospheres. Maximum conductivities of 13.8 mS cm-(1) at 275 degrees C under dry H-2 and 35.5 mS cm(-1) at 225 degrees C under wet H-2 respectively were obtained. (C) 2009 Elsevier B.V. All rights reserved.
