Abstract
The chemical degradation of SP/CL/TAP membrane had been studied using accel�erated stress test (AST) to reduce the testing time for membrane degradation. The membrane was prepared using solution intercalation method. The membrane was immersed into Fenton Reagent solution (5% H2O2, 50 ppm F eSO4) as a function of time in order to simulate the chemical radical attack on the membrane inside DMFC system. The commercial Nafionr 117 was used as reference membrane. It was found out that the SP/CL/TAP membrane weight reducedby 6% after be�ing immersed in Fenton Reagent for 6 hours. FESEM image of the SP/CL/TAP and Nafionr showed severed development of pinholes on the surface of the mem�branes after 6 hours of degradation. Both of the membranes showed similar proton conductivity deterioration behaviour; SP/CL/TAP proton conductivity dropped from 5.76x10−4 S/cm to 3.36x10−4 S/cm, while Nafionr dropped from 7.46x10−4 S/cm to 5.20x10−4 S/cm under 3 hours degradation testingand remained constanttowards the end of the testing. This shows that the performance of the SP/CL/TAP mem�brane under DMFC severe degradation environment was found comparable to the commercial Nafionr membrane. Thus, it can be concluded that the SP/CL/TAP membrane is a potential proton exchange membrane for long term usage in DMFC system.
