COMPARISON OF STRESS GENERATING MECHANISMS IN A PLANAR SOLID OXIDE FUEL CELL STACK

摘要

An understanding of the significance of the mechanical stresses within the fuel cell stack is required to design a fuel cell which will not exhibit poor performance or reduced lifetime. This paper gives a summary of the mechanisms responsible for generating stresses in the planar SOFC and details of attempts which have been made to quantify these stresses. Failsafe diagrams for informing design choices are discussed.
