Abstract
The present invention is directed generally to an electrochemical apparatus for oxidation or consumption of a fuel, and the generation of electricity, such as, a solid electrolyte fuel cell. The electrochemical apparatus ( ) comprises at least one cell ( ), wherein the cell ( ) has a solid electrolyte ( ) disposed between an oxygen electrode ( ) and a fuel electrode ( ), and at least one separator ( ) contacting the surface of one of the electrodes ( ) opposite of the electrolyte ( ). At least one electrode ( ) of the cell ( ) defines a micro-channel pattern ( ), wherein the micro-channel cross-section is preferably varied, such that reactant gas flowing through the micro channels achieves tailored local flow, pressure, and velocity distributions.
