在这项研究中,一个三维的,稳态的,非等温的数值模型的高温质子交换膜燃料电池(HT-PEMFC)与新型磺化聚苯并咪唑(SPBI)膜运行。根据实验数据关联了不同磺化度的磷酸掺杂SPBI膜的质子传导率。预测的SPBI膜和电池性能的电导率同意合理的实验数据。结果表明,具有较高水平的磷酸掺杂的SPBI膜获得更好的电池性能。较高的操作温度或压力也有利于电池性能。在双极板的肋下的电化学反应速率大于在流动通道下的值,这表明电荷传输相对于质量传输的重要性和主导性。
In this study, a three-dimensional, steady-state, non-isothermal numerical model of high temperature proton exchange membrane fuel cells (HT-PEMFCs) operating with novel sulfonated polybenzimidazole (SPBI) membranes is developed. The proton conductivity of the phosphoric acid doped SPBI membranes with different degrees of sulfonation is correlated based on experimental data. The predicted conductivity of SPBI membranes and cell performance agree reasonably with published experimental data. It is shown that a better cell performance is obtained for the SPBI membrane with a higher level of phosphoric acid doping. Higher operating temperature or pressure is also beneficial for the cell performance. Electrochemical reaction rates under the ribs of the bipolar plates are larger than the values under the flow channels, indicating the importance and dominance of the charge transport over the mass transport.
