Cross-linked poly(ether ether ketone) membranes sulfonated on both backbone and pendant position for direct methanol fuel cells |
| 초록 |
A series of cross-linkable poly (ether ether ketone)s (PEEKs) with sulfonic acid groups the backbone and pendant were synthesized successfully and used to prepare polymer electrolyte membranes for fuel cells. The results indicate that the proton conductivity of the membranes increases with increasing DS. The conductivity of the cross-linked PEEK membrane with a 60% DS is better than that of Nafion 117 at 40 C (0.053 S cm1) and even at 80 C (0.119 S cm 1). The methanol permeability of the cross-linked PEEKs with sulfonic acid groupon the backbone and pendant membranes is much lower than that of Nafion 117 membrane.Those DS effects on membrane properties are closely related with the ionic cluster dimension of membrane revealed by small angle X-ray (SAXs) pattern. The membranes were strong and tough enough to be used as functional proton exchange membrane materials. |
