摘要： In one embodiment, there is provided a fuel cell evaluator for evaluating a characteristic of a fuel cell based on a frequency characteristic of impedance of the fuel cell. The evaluator includes: an impedance acquisition unit configured to acquire impedances of the fuel cell for a certain current value in a Tafel region by changing a measurement frequency; an extraction unit configured to extract a reaction resistance from the acquired impedances; a calculator configured to calculate the product of the reaction resistance and the certain current value; and an indicator configured to indicate the product calculated by the calculator as the frequency characteristic of the impedance of the fuel cell.
