| 摘要 |
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 (1) comprises at least one cell (2), wherein the cell (2) has a solid electrolyte (10) disposed between an oxygen electrode (8) and a fuel electrode (12), and at least one separator (6) contacting the surface of one of the electrodes (13) opposite of the electrolyte (10). At least one electrode (13) of the cell (2) defines a micro-channel pattern (26), 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.
