Solid electrolyte type fuel cell having gas from gas supply ducts impinging perpendicularly on electrodes

Abstract

A solid electrolyte type fuel cell for generating electric power. The solid electrolyte type fuel cell includes two plate-shaped solid electrolyte type fuel cell elements formed with a plurality of recesses and a gas supply member for supplying an electric power generating gas to the fuel cell. The gas supply member is provided with gas supply openings for the electric power generating gas and arranged between the plate-shaped solid electrolyte type fuel cell elements so that the gas supply openings open in the recesses. When the electric power generating gas is supplied into the recesses from the gas supply openings, the streams of the electric power generating gas impinge against electrodes exposed in the recesses so as to turn their flowing directions to cause the streams to flow along surfaces of the electrodes. As a result, the temperature distribution in the fuel cell becomes uniform so that the electric power generating efficiency can be improved.
