Characterization of sulfonated poly (aryl ether sulfone) membranes with sulfated zirconia for high temperature fuel cells |
| 초록 |
Composite membranes based on sulfonated ploy (aryl ether sulfone) (SPAES) with various sulfated zirconia (s-ZrO2) contents were synthesized for PEM fuel cell applications at high temperature above 100 oC. The s-ZrO2 was prepared to improve the hygroscopic property and the proton conductive property using a sol-gel process. The presence of the s-ZrO2 additive, when uniformly dispersed at nano particle size in the organic matrix, may favorably affect the proton conductivity because the strongly bound water on the s- ZrO2 can make H+ transfer charnels effective. This results in improved proton conductivity through proton pathways even at high temperature. The composite membranes with various s-ZrO2 contents were characterized by water uptake, IEC, SEM, XRD, FT-IR, and TG-MS. The SPAES membrane with 5 wt% s-ZrO2 was employed to performer under various humidity levels for high temperature PEMFCs. |
