HIGH PERFORMANCE CATHODE WITH CONTROLLED OPERATING TEMPERATURE RANGE

摘要

In a solid oxide fuel cell having an anode, a cathode, and a dense electr olyte disposed between the anode and the cathode, the cathode having a ceram ic-ionic conducting phase of a plurality of ionic conducting particles and a metallic phase of a plurality of metallic particles. The metallic phase inc ludes a metal alloy having an oxide-to-metal transition temperature in the r ange of about 600EC to about 800EC. With this cathode, solid oxide fuel cell operating temperatures as low as about 600EC may be possible.
