The Combined Effects of Water Transport on Proton Exchange Membrane Fuel Cell Performance
A complete set of equations of two-phase water flow within the cathode, anode and membrane for one- dimensional single cell model are developed. Calculations of integrals are only needed in the membrane and the two-phase region of cathode diffuser. The proposed approach greatly reduces the complexit...

| description | A complete set of equations of two-phase water flow within the cathode, anode and membrane for one- dimensional single cell model are developed. Calculations of integrals are only needed in the membrane and the two-phase region of cathode diffuser. The proposed approach greatly reduces the complexity of the model equations, and only iterations of a single algebraic equation are required to obtain final solutions. The combined effects of water transport on proton exchange membrane fuel cell performance are represented in the polarization curve. The simulation results show that higher amount of water may helpful for membrane hydration, but not good for cathode flooding. Hereby, optimal values of temperature, relative humidity, air stoichiometry and pressure can be obtained. |
