Evaluation of Haynes230 for Solid Oxide Fuel Cell Interconnect Application

2008

National audience; Abstract - Interconnects are among the most critical parts for commercialization of SOFCs. They separate the fuel and oxidant gases and provide electric connection between the anode and cathode of adjacent cells. A Ni-based alloy, Haynes230 alloy, was evaluated in this work as a candidate material for SOFC interconnects application. During operation, a scale of chromia forms on Haynes230. Unfortunately, this scale can degrade the fuel cell performances. Thus, protective coatings are required to increase long-term stability. In this study, a nanometric layer made of reactive element oxide (La2O3, Nd2O3 and Y2O3) was applied on alloy surface by MOCVD. Perovskite oxides, suc…
