Standardization in SOFC Testing

Abstract

The fuel industry has begun to pursue standardization of testing methods to enable comparison of results among participants: within laboratories, among different institutions, and perhaps most importantly, between supplier and customer. The solid oxide fuel cell (SOFC) industry has lagged in this pursuit, partially because of the uncertain relationship between material parameters, processing and performance, and partially because individual players have adopted individual testing methodologies. The lack of testing standardization has lead to poor communication within the industry, inconsistent materials and component performance and to skepticism over results that are presented in various forums. This paper offers methods to enhance comparability of results in the SOFC industry, including industrial efforts to standardize performance testing of SOFC trilayers, both in button format and moderate sized planar sheets.
