| 摘 要： | 制备了聚2-丙烯酰胺-2-甲基丙磺酸（PAMPS）质子交换膜并对其进行交联改性,研究了膜的含水率、溶胀率、拉伸强度、高温保水率、质子电导率等性能.结果表明,PAMPS均质膜的质子导电率很高（0.32 S/cm）,但溶胀率过高、机械强度差.交联改性后,膜保持高的导电率（3% MBA,0.076 S/cm）和高温保水性能,且膜的溶胀率大幅度降低,机械强度显著提高（3% MBA,23.6 MPa）.

| Abstract: | Poly-2-acrylamido-2-methyl propane sulfonic acid(PAMPS) proton exchange membrane and cross-linking PAMPS were prepared for PEM fuel cell.The water content,dimensional change,mechanical property,high temperature water retentivity and proton conductivity of the membranes were investigated.It was found that the PAMPS membrane had high proton conductivity(0.32 S/cm),but high dimensional change and low mechanical property.After cross-linking,the membranes had high water retentivity in high temperature and high proton conductivity(3% MBA,0.076 S/cm),but low dimensional change and high mechanical property(3% MBA,23.6 MPa). |
