Electerochemical study of sulfonated poly ether ether ketone nanocomposite membrane for direct methanol fuel cell application

High methanol permeability and expensive price of current commercial Nafion® membrane for direct methanol fuel cell (DMFC) have encouraged researchers to modify proton exchange membrane (PEM). Sulfonted poly ether ether ketone (SPEEK) is a polymer which attracted a lot of attention recently. This st...
