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.
