Abstract
An electrode supported electrolyte membrane includes an electrode layerfacing an electrolyte layer. The opposing side of the electrode layerincludes a backing layerof a material with a thermal expansion coefficient approximately equal to the thermal expansion coefficient of the electrolyte layer. The backing layeris in a two dimensional pattern that covers only a portion of the electrolyte layer. An electrochemical cell such as a SOFC is formed by providing a cathode layeron an opposing side of the electrolyte layer
