PROBLEM TO BE SOLVED: To provide a cell for a fuel cell that can precisely detect reduction of hydrogen concentration damaging the electrodes of the fuel cell, and can monitor the hydrogen concentration with a small size and simple device for a safe operation of the fuel cell. SOLUTION: The cell consists of a high polymer film, and an electrode carbon metal and a separator provided at both sides of the high polymer film, respectively. A reaction gas path is formed to a gas outlet from a gas inlet in the cell, and a hydrogen concentration detector is provided just in front of the gas outlet of the reaction gas path. |
