Supporting electrodes for solid oxide fuel cells and other electrochemical devices

摘要

An electrode supported electrolyte membrane includes an electrode layer 630 facing an electrolyte layer 620 . The opposing side of the electrode layer 630 includes a backing layer 640 of a material with a thermal expansion coefficient approximately equal to the thermal expansion coefficient of the electrolyte layer 620 . The backing layer 640 is in a two dimensional pattern that covers only a portion of the electrolyte layer 630 . An electrochemical cell such as a SOFC is formed by providing a cathode layer 610 on an opposing side of the electrolyte layer 620.
