摘要
双极板对质子交换膜燃料电池的性能有重要的影响。它们是确保反应介质进入电池的媒介,而且双极板在很大程度上决定了燃料电池电堆的重量。因为重量和材料成本有直接关系,因此,双极板对燃料电池的制造成本有决定性作用。在目前的燃料电池产品中,双极板的质量可高达70%,并占电池成本的30%。增强复合双极板有独特的电学和机械性能,若解决团聚和相容性等技术问题可显著提高双极板的性能。导电聚合物复合的含碳纳米材料显示出改善双极板性能的良好前景。本综述研究重点讨论双极板中主要材料对其电气,机械和耐久性能的影响。
Bipolar plates have an important influence on the performance of PEMFC.They are the medium to ensure that the reaction medium enters the cell,and the bipolar plate determines the weight of the fuel cell stack to a large extent.Because the weight is directly related to the material cost,the bipolar plate plays a decisive role in the manufacturing cost of fuel cells.in the current fuel cell products,the quality of bipolar plate can be as high as 70%and accounts for 30%of the cost of the cell.The enhanced composite bipolar plate has unique electrical and mechanical properties.If the technical problems such as agglomeration and compatibility are solved,the performance of the bipolar plate can be significantly improved.Carbon-containing nanomaterials composite with conductive polymers show a good prospect to improve the performance of bipolar plates.This review focuses on the effects of the main materials on the electrical,mechanical,and durability of bipolar plates.
