Synthesis and Properties of BaSn_(0.75)B_(0.25)O_(3-d)(B=La,Gd,Y,In…) Proton Conductors

1 Results We study the synthesis,the structural and transport properties of acceptor-doped barium stannate BaSn0.75B0.25O3-d (B=La,Y…) compounds.Some of these materials were presented few years ago as good proton conductors with some interest for the fuel cell community1-2].Nevertheless,these studies were only limited to two kinds of dopants and the elaboration was far from being optimised leading to poor properties.So the main objective of the present study is to extend the study of acceptor-doped bar...
