Fuel-cell device utilizing surface-migration on solid oxide

摘要

The present invention relates to a fuel-cell device utilizing surface-migration on solid oxide wherein a cathode layer and an anode layer are arranged in parallel to each other on one surface of the substrate. A strip-shaped cathode layer formed from SSC or the like and a strip-shaped permeable anode layer formed from a rhenium metal powder or the like are arranged in parallel and spaced apart from each other on one surface of the substrate. A fluid fuel such as ethanol is fed to the entire surface of the anode layer so as to permeate therethrough. Oxygen ions formed at the cathode layer exposed to the atmosphere migrate over a surface region on the substrate and react with the fuel species supplied to the anode layer. The cathode layer and the anode layer formed on the substrate together constitute a fuel cell.
