Preparation and Properties of SeO2 and PWA Binary Compound Doped SPEEK Proton Exchange Membranes
International Journal of Electrochemical Science, 2018 Herein, we prepared proton exchange membranes by adding SeO2 and phospho-wolframic acid (PWA) into DS 85 wt% sulfonated polyether ether ketone (SPEEK). The result indicates that their proton conductivity is increasing without decrease of their methanol ...
