Polymer electrolyte membrane fuel cells (PEMFC) are considered as great alternative energy sources in diverse areas. In the PEMFC system, the performance of proton exchange membrane plays an important role. Proon exchange membrane works for pathway of proton and seperator between anode and cathode. Some oxigen is changed to hydroxy radical, when react with proton on cathode side. Hydroxy radical could be reason of degradation of membrane. To remove hydroxy radical, Ce is introduced to membrane for radical quencher. So, sPEEK/Ce quencher composite membrane was prepared and their properties such as fenton test, proton conductivity, water uptake, methanol crossover, and etc. were measured |
