摘要： Provided is a fuel cell, the output voltage of which is improved by making a membrane moist state uniform. An anode-side gas diffusion layer and a cathode-side gas diffusion layer are joined to a membrane electrode assembly, and a separator is joined to the anode-side gas diffusion layer. The separator has a recess portion and a protrusion portion formed to constitute a gas flow path and a refrigerant flow path, respectively. The cross-sectional area of the recess portion is made relatively small at the downstream side in comparison with that at the upstream side, and the cross-sectional area of the protrusion portion is made relatively large at the downstream side in comparison with that at the upstream side, thereby improving the moist state.

Since such judgment is performed, as compared with the conventional technology, the internal state of the fuel cell can accurately be grasped, and highly efficient and highly robust control of the fuel cell system can be performed.

摘要： A fuel cell system according to the present invention is characterized by comprising a measurement unit which measures an impedance of a fuel cell in a predetermined frequency region, and a regulation unit which regulates an amount of a gas to be supplied to the fuel cell based on a measured value of the impedance in the predetermined frequency region. According to such a constitution, the impedance of the fuel cell in the predetermined frequency region (e.g., a low frequency region) is measured, and the amount of the gas (e.g., an amount of an oxidizing gas) to be supplied to the fuel cell is regulated based on this measured value of the impedance. Here, since the impedance of the fuel cell in the predetermined frequency region largely differs with a fuel supply state (see FIG. 2), the amount of the gas to be supplied to the fuel cell can be regulated based on the measured value of the impedance to realize a highly efficient and stable operation.
