Abstract

Chemical compatibility and cation interdiffusion between the double perovskite cobaltites R BaCo 2 O 6−δ ( R = Gd, Pr) and proton-conducting electrolyte BaZr 0.8 Y 0.2 O 3−δ were studied. Chemical interaction was found to occur already at 1100 °C as a result of the partial dissolution of R BaCo 2 O 6−δ ( R = Gd, Pr) in BaZr 0.8 Y 0.2 O 3−δ . Analysis of the element distribution along the cross sections of diffusion couples R BaCo 2 O 6−δ ( R = Gd, Pr)|BaZr 0.8 Y 0.2 O 3−δ showed strong interdiffusion of cations, with cobalt being the most mobile one. Its diffusion depth in the electrolyte reaches up to several hundreds of micrometers. The addition of NiO as a sintering aid to BaZr 0.8 Y 0.2 O 3−δ promotes cation diffusion especially through the grain boundary mechanism, increasing the diffusion depth of Co. The possible implications of cation interdiffusion on the performance of proton-conducting SOFCs are discussed based on the results obtained.
