Three Dimensional Large Scale Numerical Simulation of PEMFC with Low-Pt Loading

Article of Honda R&D Technical Review Vol.28 No.1

Summary

The developed multiphase mixture model for low-Pt loading electrode is applied to examine the effects of Pt loading and operating condition on current density and water distribution in realistic scale proton exchange membrane fuel cells. The predicted fuel cell voltage, high-frequency resistance, as well as current density and temperature distributions all show good agreement with the experimental data under various operating conditions and for two Pt loadings of 0.3 mg/cm2 and 0.1 mg/cm2. In particular, the present study demonstrates quantitative comparisons of the liquid water distribution in the proton exchange membrane fuel cell with the neutron imaging measurements. Such a comprehensive data comparison gives a fundamental understanding of the physical phenomena in the proton exchange membrane fuel cells and findings to design and develop the next generation of proton exchange membrane fuel cell with low-Pt loading.
