| Abstract |
Materials engineering plays vital role in Solid Oxide Fuel Cell (SOFC) technology. For example,
engineered porous materials are needed to support delicate electrolyte membranes, where
mechanical integrity and effective diffusivity to fuel gases is critical; and to construct fuel cell
electrodes, where an optimum combination of ionic conductivity, electronic conductivity, porosity
and catalyst distribution is critical. Material engineering also underpins selection of cell designs and
material systems to minimise failure, particularly during transient operations such as thermal
cycling. The paper will address these issues, making reference to high temperature (>900C) SOFCs
for integration with gas turbines, and metal supported SOFCs designed to operate at temperatures of
500-600C. |
