质子交换膜燃料电池双极板材料的研究

Materials for Bipolar Plates in Proton-exchange Membrane Fuel Cells

双极板是质子交换膜燃料电池的关键部件之一，具有隔离反应介质、收集电流、提供气体通道的作用。寻找性能低且成本优良的双极板材料已成为质子交换膜燃料电池产业化技术研究中的重要课题。综述了各种双极板材料的优缺点，提出了双极板材料的发展方向。

Bipolar plate is one of the key components for proton-exchange membrane fuel cells（PEMFC）, which has the functions of isolating reactants, collecting current and providing channels for reaction gas. The important task of PEMFC industrialization is to look for better-capability and low-cost bipolar plate materials. The advantage and disadvantage of various materials are reviewed, and the future developing trend is discussed.
