<P>PROBLEM TO BE SOLVED: To provide a characteristic evaluation method of a fuel cell using an equivalent circuit model, which expresses characteristics of the fuel cell as an electrical circuit easily available in simulation software. <P>SOLUTION: The characteristic evaluation method of a fuel cell evaluates electrical characteristics of the fuel cell by fitting the fuel cell to an equivalent circuit model. In the equivalent circuit model, a plurality of circuits each of which is formed by connecting a resistor and a capacitor in parallel are connected in series, and, the resistor is a nonlinear resistor whose resistance value varies as a function of an electric current flowing in the resistor. <P>COPYRIGHT: (C)2009,JPO&INPIT |
