Chemically-induced stress of fuel cell laminate under oxidizing/reducing gradient condition

Research output: Contribution to conferencePaperpeer-review

Abstract

Fracture conditions were examined by conducting stress analysis, using the finite element method and taking into account the chemically-induced expansion of nonstoichiometric oxide. Based on this stress analysis, it was found that residual stress at fabrication of the fuel cell laminate and thermal stress under high-temperature conditions were small, but stress due to chemically-induced expansion of nonstoichiometric oxide exceeded the fracture stress of the component materials. This showed that stress due to chemically-induced expansion was the main cause of the fracturing observed in this research.
