Simulation of mass and heat transfer in an evaporatively cooled pem fuel cell

HIGHLIGHTS

SUMMARY

Liquid water inside the cell can accumulate from condensation of the vapor coming from the humidified gas streams in addition to the chemical production of water at the cathode CL at high current densities. No measurements were done or are possible for the distribution of temperature and relative humidity inside the cell, evaporation along the HPILs, water vapor transport paths and level of membrane humidification. The macro-homogeneous modeling approach has been frequently used as a method to investigate the different coupled transport phenomena in PEMFCs (e_g, ). The macro-homogeneous modeling approach has continuously . . .
