Highly Proton Conductive sPPEK /SSi-GO Composite Membranes for Proton Exchange Membranes Fuel Cells

Our work has focused on the development of polymer electrolyte materials, and the membranes for the potential application of AEMFC, PEMFC, redox flow battery, and other electrochemical energy fields. Alkaline anion exchange membrane fuel cells (AEMFCs) attract much attension because they could utilize non-noble metals as catalysts, such as Ni, Ag peroxide. Furthur, SSi-GO based composite membranes was prepared with SPPEK aimed at the establishment of the ionic transport channel. The proton conductivity of 10% content composite membranes reached 0.094 S/cm at 30℃, and 0.220 S/cm at 80℃ much higher than Nafion 117, which indicated the potential application of SPPEK-SSi-GO composite membranes for PEMFC.
