Modelling heat and water management in PEM fuel cell

This thesis covers the simulation and the comparison of the experimental results inof single-cell proton exchange membrane fuel cell (PEMFC) with using Fluent PEMFC module. The PEMFC is made up of nine layers which consist four layers for the anode and cathode sides; current collector, gas channel gas diffusion layer and catalyst layer, and the membrane between the anode and cathode. Water and heat management can be provided by keeping hydrogen flow rate, oxygen flow rate, cell temperature, and humidification temperature under control. The effects of hydrogen flow rate, oxygen flow rate, cell temperature and humidification temperature on power density is examined by the experimental study.It is found that temperature has an important effect on the performance of PEM fuel cell by the results of experimental study. The increasing temperature increases the performance of the system increases. Even though after exceeding a definite temperature cell performance decreases.
