| 제목 | The modification of sulfonated poly(arylen ether ketone) membrane for direct methanol fuel cell |
| 초록 | Fuel Cell converts chemical energy of fuel into electrical energy with high efficiency and low emission of pollutants. Among many types of fuel cell, Direct Methanol Fuel Cell is interesting for the mobile and domestic application due to low operating temperature, no leak problem, and fast start-up and easy fuel storage and transportation. Perfluorinated membrane such as Nafion(from Du-pont) has been used as the polymer electrolyte membrane. Nafion has good conductivity and thermal, mechanical properties. But Nafion can not be used for Direct Methanol Fuel Cell due to high methanol crossover. Sulfonated poly(aryl ether ketone)(sPAEK) membranes were prepared by casting method. Modified composite membranes were also made by the blend of Nafion /sPAEK to form coating layer through casting method. The morphology of modified membranes was studied by means of scanning electron microscopy(SEM). In the blend solution, as the Nafion was more rich , delamination between membrane and coating layer was occurred. On the other hand, when the blend ratio of Nafion/sPAEK was equal or the sPAEK was more rich, delamination was not occurred and Naifon domains were formed in sPAEK matrix. The surface morphology was also studied by means of atomic force microscopy(AFM). By changing the blend ratio of coating layer, the morphology and property of modified membranes could be controlled. 1. Peixiang Xing, Gilles P. Robertson Michale D. Guiver, Serguei D.
