Evaluation of Sr_1-xRE_xTiO_3+d perovskites (RE=Rare earth metals) as anodes in sulfur-based hybrid cycle for hydrogen

Abstract

A sulfur-based hybrid cycle for electrolysis and thermal decomposition in high temperature gas-cooled reactor is considered to be a highly efficient hydrogen producing process. The electrodes must satisfy the following requirements; (i) high corrosion resistance in H₂SO₄ solution,and (ii) high electrical conductivity, In this study, electrical conductivity and corrosion resistance in H₂SO₄ solution of A-site doped SrTiO₃ perovskites will be reported.
