    Abstract

    This paper presents the development of a comprehensive model of fuel cell electrochemical performance which incorporates not only a general definition of area specific resistance (ASR), but electronic shorting, leakage and other current loss mechanisms. The comprehensive model is demonstrated in this paper for an anode-supported solid oxide fuel cell. The emphasis here is to show the possible effects of electronic shorting and its relationship to performance. The goal is to show or predict the range and extent of possible effects on performance. Through the developed approach, the relationship between shorting and ASR relationship was investigated. ASR can actually go down with increased electronic shorting since current effects ASR.
