<P>PROBLEM TO BE SOLVED: To provide a kinetic parameter calculation method capable of calculating in a high accuracy a kinetic parameter even if there is a limitation in an experiment system of a half cell measurement. <P>SOLUTION: Electrical characteristics of a fuel cell are measured while changing a hydrogen supply amount to the fuel cell under a half cell condition and then a degree of the change of the electrical characteristics of the fuel cell against the change of the hydrogen supply amount. Further, out of the electrical characteristics of the fuel cell extracted, based on the measurement, a range with small dependence on the hydrogen supply amount is chosen as a fitting region. Then, fitting is performed by making identical an experimental value obtained by the half cell measurement of the fuel cell in the above chosen fitting region and a theoretical value, and a kinetic parameter is calculated. <P>COPYRIGHT: (C)2011,JPO&INPIT |
