چکیده مقاله
Due to the increasing level of air pollution and the reduction of fossil fuels, the need for new technologies and alternative fuels is felt more than ever Proton exchange membrane fuel cells PEMFCs are one of these technologies, which have been of great interest to the researchers due to the benefits of non contamination, high efficiency, fast start up, and high power density The proper functioning of the fuel cell requires thermal management and water management within the cells To this end, in this work, the effect of different parameters on the performance of PEM fuel cell was investigated The results demonstrated that the performance of the cell increases with increasing the pressure in the low current densities, while in the high current density, performance decreases with increasing the pressure of the cell Also, the study of the effect of relative humidity shows that increasing the relative humidity of the cathode does not have much effect on the performance of the cell while increasing the relative humidity of the anode improves the performance of the cell
