摘要：
A novel dense Mg2+-doped SnP2O7-SnO2 composite ceramic (5 mol % Mg2+) was prepared through an effective preparation method.The composite phases of SnO2 and SnP2O7 in the ceramic were determined by XRD method. The result of SEM image indicated that the composite ceramic is very dense. The H-2/air fuel cell using the sample as an electrolyte generated the maximum power densities of 39.69 mW cm(-2) at 150 degrees C. 66.89 mW cm(-2) at 200 degrees C and 93.71 mW cm(-2) at 250 degrees C, respectively. The result indicated that Mg2+-doped SnP2O7-SnO2 composite ceramic is a promising solid electrolyte for intermediate temperature fuel cells. Crown Copyright (C) 2012 Published by Elsevier B.V.
