Abstract: A fuel cell system has a cell (1) that is capable of generating electric power. The cell (1) has a fuel electrode (1a), an air electrode (1b) and an electrolyte (1c). The fuel electrode (1a) is supplied with hydrogen obtained by reforming fuel gas. The air electrode (1b) is supplied with oxygen in the air. The electrolyte (1c) is interposed between the fuel electrode (1a) and the air electrode (1b) to enable oxygen ions to pass through to the fuel electrode (1a). A water vapor retaining mechanism (6) is disposed in a flow path of the fuel gas supplied to the fuel electrode (1a). The mechanism (6) retains water vapor generated in the fuel electrode (1a) during electric power generation by the cell (1). The mechanism (6) enables the water vapor to be mixed with the fuel gas.

Abstract: A fuel cell system has a cell 1, generating power, with a fuel electrode 1a, an air electrode 1b, and an electrolyte 1c. A water vapor retention member 11 is disposed on a communication path for the fuel gas supplied to the fuel electrode 1a. The retention member 11 retains water vapor, generated by the fuel electrode 1a along with power generation by using the cell 1 and mixes the water vapor with the fuel gas. The retention member 11 has a reforming catalyst that enables the hydrogen, generated by reacting the fuel gas, to be supplied. Exhaust ports 13a exhaust fuel gas toward positions on a surface of the water vapor retention member 11.
