摘要
质子交换膜燃料电池(PEMFC)中的双极板起到传递电子、分配气体、电池内水管理、支撑膜电极组件等作用,也是保证燃料电池堆低成本的关键部件.本文对双极板材料(金属、石墨和复合材料)、作用、优势及挑战进行了分析,其中复合石墨双极板以其长寿命和耐腐蚀的特质,具备与其他双极板竞争的优势,近年来受到高度关注;对石墨形成导电网络的相关因素(涉及填料尺寸、形态,辅助填料桥接石墨颗粒)、聚合物的成分与固化条件以及成型工艺条件对性能的影响规律进行了讨论.未来,开发具有优异综合性能的复合石墨双极板,掌握并优化聚合物结构及反应路径对其性能的平衡作用,使现有配方及成型方法适应大规模生产,将大大增强质子交换膜燃料电池在更多领域的大规模应用.
Abstract
Bipolar plates play a role in electron transfer,gas distribution,water management,supporting membrane electrode assembly in the proton exchange membrane fuel cell(PEMFC)and is also a key component to ensure low cost of fuel cell stack.In this paper,bipolar plate materials(metal,graphite and composite materials),functions,advantages and challenges are reviewed.Among them,the composite graphite bipolar plate stands out with its long cycle life and high corrosion resistance,and has received high attention in recent years.The factors related to the conductive network formed by graphite(including the size and shape of filler and the auxiliary filler bridging graphite particles),the composition and curing conditions of polymer,and the influence of the molding process conditions on the properties were discussed in this paper.In the future,the development of composite graphite bipolar plates with excellent comprehensive performance,making existing formulas and forming methods suitable for large-scale production by mastering and optimizing the balance between polymer structure and reaction path on their performance,will greatly enhance the large-scale application of proton exchange membrane fuel cells in more fields.
