摘要

PPROBLEM TO BE SOLVED: To provide a method of creating a particle size distribution model more precisely in a shorter computation time, a method of predicting a degradation of a fuel cell catalyst using the method of creating the size distribution model, and a method of controlling a fuel cell using the method of predicting the degradation of the fuel cell catalyst. PSOLUTION: The method of creating the particle size distribution model includes: a particle size range determining step; an integrating step of integrating the frequency of appearance of particles within the particle size range determined in the particle size range determining step; a division point determining step of determining particle sizes which provide division points, by using the integral of the frequency of appearance obtained in the integrating step; and a typical point determining step of determining the minimum particle size, the maximum particle size and the particle sizes of the division points as typical points. This method is characterized by assuming a particle size distribution which contains particles having the particle sizes of the respective typical points and is plotted such that the frequency of appearance of the particles having the particle size of each of the typical points is equal to the integral over each of the regions defined by the typical points, and by obtaining the assumed particle size distribution as a particle size distribution model.
