Abstract
A three-dimensional model for a high temperature polymer electrolyte membrane (PEM) fuel cell having an active area of 25 cm(2) is developed. Triple mixed serpentine flow channel single cell with phosphoric acid doped polybenzimidazole (FBI) membrane is used in the model. Steady-state, isothermal, single phase assumptions are defined for the system. The model is simulated at different temperatures ranging from 100 to 180 degrees C to investigate the influence of operation temperature on the performance of the cell. It is seen that there is an improvement in the performance of the cell as the operation temperature increases. Experimental data are used to validate the model both for single channel and triple mixed serpentine flow channel. Current density distribution is obtained at different operating voltages. The predicted results show that at high operating voltages the local current density is almost uniform; whereas, decreasing operating voltage causes non-uniformities in the local current density.
