Development of Cell Voltage Model PEM Fuel Cell using group contribution method |
| 초록 |
A new group-contribution model based on the modi2ed double-lattice theory is developed and applied to describe vapor-liquid equilibria of solid polymer electrolyte/water systems. The proposed model includes the combinatorial energy contribution that is responsible for the revised Flory–Huggins entropy of mixing, the van der Waals energy contribution from dispersion, polar force and the speci2c energy contribution. Quantitative description according to the proposed model is in good agreement with experimentally observed water activities of polymer electrolyte fuel cell systems. And we established cell voltage model for PEMFC as function of current density using group contribution method. |
