摘要

提出一种基于正交实验和熵权法的多因素、多目标优化方法，研究旋转角速度（ω）、工作温度（T）、相对湿度（RH）和工作压力（P）等参数对旋转质子交换膜燃料电池（R-PEMFC）性能指标的影响，并通过多目标综合评价R-PEMFC的性能。结果表明，不同参数对不同性能指标有不同程度的影响。此外，通过熵权法确定了各性能指标的权重，其中有效传质系数的权重最大，占 24.11%，其次是氧均匀性指数、净功率密度、温差和电流密度均匀性指数，分别占 18.99%、16.10%、15.66% 和 15.47%，压降的权重最小，仅占 9.67%。最后，根据权重对正交实验方案进行综合评分，得出最佳ω为 1080 rpm，T 为 353 K，RH 为 50 %，P 为 1.6 atm。该研究提供了一种多目标优化方法和评价思路，对进一步提高 R-PEMFC 的性能具有参考价值。

Investigation of rotary proton exchange membrane fuel cell performance optimization based on orthogonal experiment and entropy weight method

A multi-factor and multi-objective optimization method based on orthogonal experiment and entropy weight method is proposed to investigate the influence of the parameters such as rotational angular speed (ω), operating temperature (T), relative humidity (RH), and operating pressure (P) on the performance indicators of rotary proton exchange membrane fuel cell (R-PEMFC), and to comprehensively evaluate the performance of R-PEMFC through multiple objectives. The results show that different parameters have various degrees of influence on different performance indicators. Moreover, the weights of each performance indicator are determined by the entropy weight method, in which the effective mass transfer coefficient accounts for the largest weight of 24.11 %, followed by the oxygen uniformity index, net power density, temperature difference and current density uniformity index accounting for 18.99 %, 16.10 %, 15.66 %, and 15.47 %, respectively, and the pressure drop accounts for the smallest weight of only 9.67 %. Finally, according to the weight, the orthogonal experimental schemes are comprehensively scored, and it is known that the best ω is 1080 rpm, T is 353 K, RH is 50 %, and P is 1.6 atm. This investigation has supplied a multi-objective optimum method and evaluate idea, which has reference value for further improving the performance of R-PEMFC.
