PROBLEM TO BE SOLVED: To provide a fuel cell.SOLUTION: The fuel cell includes an anode catalyst layer, a cathode catalyst layer, and an ion conducting membrane interposed between the anode catalyst layer and the cathode catalyst layer. A first gas diffusion layer is disposed over the anode catalyst layer, and a second gas diffusion layer is disposed over the cathode catalyst layer. An anode flow field plate is disposed over the first gas diffusion layer, and a cathode flow field plate is disposed over the second gas diffusion layer. A gas-sensing layer is interposed between the anode flow field plate and the anode catalyst layer. Characteristically, the gas-sensing layer has a first electrical resistivity when contacting hydrogen gas and a second electrical resistivity when contacting an oxygen-containing gas, the first electrical resistivity being lower than the second electrical resistivity. |
