Precise modeling of proton exchange membrane fuel cell (PEMFC) is helpful to predict its perfor-mance more accurately. In this paper, the mathematical modeling of the proton exchange mem-brane fuel cell is firstly carried out, proposing an Improved Particle Swarm Optimization (IPSO) al-gorithm, by comparing the improved particle swarm optimization (IPSO) algorithm, the basic parti-cle swarm algorithm (PSO) and genetic algorithm (GA) for the parameter estimation. The results show that the improved particle swarm optimization (IPSO) algorithm to the results of the proton exchange membrane model parameter estimation algorithm is more accurate than the other two. The polarization curves of fuel cells at different temperatures and pressures can be predicted by using the improved particle swarm optimization algorithm (IPSO). The results show that the im-proved particle swarm optimization algorithm (IPSO) has a strong searching ability and accurate searching results.
