Influence of Cell Potentials on theCathode Oxygen Concentration in a Serpentine Flow Field PEM Fuel Cell
The Proton Exchange membrane Fuel Cell (PEMFC) performance is influenced by not only on several factors as well as the operation conditions, transport phenomena inside the cell and kinetics of the electro chemical reactions. This work numerically investigated the adverse effect of an effective distribution of oxygen gases on cathode side for six different cell potentials in order to improve water management in a polymer electrolyte membrane fuel cell (PEMFC) with serpentine flow field design. The numerical results showed that higher cell potentials enhance the cell performance through the higher concentration of oxygen gages on cathode side compared than lower cell potentials.
