燃料电池聚合物电解质膜的研究进展

According to their operation temperature, polymer electrolyte membrane and fuel, the polymer electrolyte membrane fuel cells (PEMFCs) are sorted as high temperature proton exchange membrane fuel cell, low temperature proton exchange membrane fuel cell, direct methanol fuel cell and anion exchange membrane fuel cell. In this review. the advances of the polymer electrolyte membranes for these fuel cells are presented. In the first section, the four types of fuel cells are introduced briefly. In the second section, the model of Nafion membrane is discussed and a revised model based on parallel water-channel (inverted-micelle cylinder) model at mesoscopic scale is proposed. Then the modified strategies of Nafion for proton exchange membrane fuel cells and DMFCs are described. Lastly, the strategies of preparing proton exchange membranes alternatives to Nafion are presented. Furthermore, the highlights of them are also listed. In the third section, the development of anion exchange membranes is given. In the last section, the research trends of this field in the future are predicted.
