Simulation study for 3D dynamic characteristics of voltage losses in PEM fuel cell

Fuel cells, providing an advanced alternative energy source, are devices that can convert chemical into electrical energy. Modeling of a fuel cell provides improvements to the design cells as well cheaper, better and more efficient cells. Three basic voltage losses occur in cell: activation polarization, ohmic polarization concentration polarization. In this study, simulation PEM (proton exchange membrane) was performed by using Matlab@Simulink program. Polarization power curves were obtained for different operating temperatures considering these losses.
