在这里，我们介绍了一种改进的活化过程中使用的三步方法结合冷却后停止技术的质子交换膜。沿着了每个步骤的详细信息和依据以及中间结果。通过仔细优化活化过程的每个步骤的操作温度，可以提高新制造的燃料电池的性能并且降低可变性。此外，我们表明，冷却后停止技术可以稳定和提高燃料电池的性能。改进的三步法的最大电流密度为1008mAcm−2，比一步法的880mAcm− 2提高了14.5%。
Here we introduce an improved activation process using a three-step method in conjunction with a cooling-after-a-stop technique for proton exchange membranes. Detail information and rationale for each step is presented along with intermediate results. By carefully optimizing the operation temperature of each step of the activation procedure, the performance of a newly fabricated fuel cell can be increased and the variability decreased. In addition, we show that the cooling-after-a-stop technique can stabilize and improve fuel cell performance. The improved three-step method results in a maximal current density of 1008mAcm−2, an increase of 14.5%, compared to the 880mAcm−2achieved by the one-step method.
