Abstract
A solid oxide fuel cell is formed by arranging a fuel electrode layer and an air electrode layer on both surfaces of a solid electrolyte, respectively, a fuel electrode current collector and an air electrode current collector outside the fuel electrode layer and the air electrode layer, respectively, and separators outside the fuel electrode current collector and the air electrode current collector. A fuel gas and an oxidant gas are supplied from the separators to the fuel electrode layers and the oxidant electrode layers, respectively, through the fuel electrode current collectors and the air electrode current collectors, respectively. Alternatively, indents are provided on the surface of each of the separators, which surface is in contact with one of the current collectors, to increase the dwell volume and hence the retaining time of the gas in the interior of the current collectors.
