Application of exsolved structures as a route to more robust anodes for improved biogas utilisation in SOFCs

Abstract

Biogas is a potentially readily available fuel which could be especially useful when combined with the efficient energy conversion in SOFCs. This could be especially important in rural or remote locations where grid electricity is not available. Biogas contains mixture of methane CO2 with inherently high levels of H2S, therefore to improve performance in biogas more robust anodes are required that are more tolerant to both carbon and sulphur. In this paper the use of catalyst nanoparticles exsolved onto porous as a possible method of producing more resistant structures is discussed. All of the options showed good performance in reformed biogas mixtures with the exsolved structures showing im..
