NUMERICAL INVESTIGATION OF TEMPERATURE DISTRIBUTION OF PROTON EXCHANGE MEMBRANE FUEL CELLS AT HIGH CURRENT DENSITY
SINOPSIS
A three-dimensional model with coolant channels was developed to investigate the temperature distribution and performance of proton exchange membrane fuel cells (PEMFCs) under the impacts of different operating conditions, including Reynolds numbers of the coolant water, current densities, and relative humidity levels of reactants. Numerical simulation results revealed that relative humidity had a significant effect either on cell performance or on temperature distribution, and the temperature of the interface between the catalyst and gas diffusion layers in the cathode was the highest of any part in the fuel cell. Limited by the temperature of the coolant, a small rise in the reactant temperature would have little influence on the overall temperature distribution. Lastly, a novel thermal resistance model was proposed to validate the rules governing temperature distribution in fuel cells.
