质子交换膜燃料电池用磺化聚醚醚酮膜的研究进展
Research progress of the sulfonated poly(ether ether ketone)s membranes for proton exchange membrane fuel cell
摘要
Abstract
The Nafion membrane generally used in proton exchange membrane fuel cell(PEMFC) possesses high proton conductivity,good thermal and chemical stability. However,its preparation cost is too high and its proton conductivity nearly decreases to zero at high temperature. This paper reviewedthe progress of sulfonated poly(ether ether ketone)(SPEEK)and SPEEK/ionic liquid(IL) modified composite membrane as one of the Nafion alternative membrane. Two preparation methods of SPEEK classified by direct sulfonation method and sulfonated monomer polymerization method were also introduced. The direct sulfonation method was easy,however,the degree of sulfonation(DS) was less than 1.0 and the reaction was difficult to control. The sulfonated monomer polymerization method was difficult and its raw material was poisonous. However,DS can be easily controlled in this way. The effect of reaction time,temperature and ratio of raw materials,sulfonated monomer species, membrane preparation process and solvent on the performance of SPEEK was also overviewed and analyzed. It was found that in the direct sulfonation method the DS was negatively correlated with temperature and positively with the reaction time,while little relationship with the ratio of raw materials. In order to improve the performance of PEMFC,critical problems such as the loss of ionic liquids and the compatibility with Pt-based catalyst which resulted in lower battery performance during fuel cells operation should be solved in the future development of SPEEK/IL modified composite membranes.关键词
