Abstract

Abstract: The performance of air compressor has a great influence on the performance of fuel cell. In order to establish the mathematical model of air compressor accurately, the nonlinear function of rotational speed, flow and pressure is established by using the equivalent circuit structure method. The mathematical model parameters of air compressor equivalent circuit and the data of air compressor performance parameters are fitted, according to the fitting effect, the method based on maximum flow deviation and outlet pressure weighting is used to improve the fitting method. The results show that the two methods can realize high precision fitting of static model.

Key words: fuel cell, air compressor, modeling, fitting method
