WATER MANAGEMENT IN CATHODE SIDE OF A PEM FUEL CELL

A one dimensional and isothermal mathematical modeling of cathode side of a Proton Exchange Membrane is implemented for water anagement consideration. The model considers one phase flow in the gas diffusion layer (GDL) and can predict the region with condensation. Homogenous distribution of wet phase (liquid water) will be assumed throughout each wet control volume as fog. A detailed discussion of numerical techniques for the PEMFC model is given with a flow diagram to provide an overview of the solution procedure. Validation is implemented to show agreement between the obtained results and existing results in the literature.
