CREEP BEHAVIOR OF GLASS/CERAMIC SEALANT USED IN SOLID OXIDE FUEL CELLS

摘要

Creep deformation of glass sealant used in Solid Oxide Fuel Cell (SOFC) under operating temperature is not negligible. The goal of the study is to develop a creep model to capture the creep behavior of glass ceramic materials at high temperature and to investigate the effect of creep of glass ceramic sealant materials on stresses in glass seal and on the various interfaces of glass seal with other layers. The creep models were incorporated into SOFC-MP and Mentat FC, and finite element analyses were performed to quantify the stresses in various parts. The stress in glass seals were released due to its creep behavior during the operating environments.
