Integration of oxide anodes into the Rolls-Royce IP-SOFC concept

Abstract

The limitations of the current state of the art Ni-YSZ cermet anodes with respect to Redox stability, coking and sulphur tolerance are well acknowledged. A material which mitigates all or even some of these issues would be of great importence for the continued development of robust SOFC systems. One such promising material system is based around the perovskite (La,Sr)Cr 0.5Mn0.5O3 (LSCM). In this paper, some aspects of the work, carried out to integrate LSCM anodes into the IP-SOFC, are described. The intricacies of the introduction of a new material into an existing stack design concept are considered and how this impacts the performance and requirements of adjacent materials. In the case o..
