Abstract A three-dimensional two-phase non-isothermal serpentine flow field PEMFC model is established by COMSOL to study the effect of rough contact interface on the performance of serpentine flow field PEMFC. The influence of contact thermal resistance on polarization curve, temperature distribution and saturation distribution of liquid water is analyzed with the contact thermal resistance among all components being coupled into the three-dimensional model. The results show that with contact thermal resistance has a significant effect on the temperature distribution of PEMFC,which improves the gas transmission and drainage capacity and provides better performance when compared with that of PEMFC without contact thermal resistance.
