The system composed of hydrocarbon membrane and Nafion-based electrode usually exhibits poor interfacial stability between the membrane and the electrode. In this work, to enhance interfacial stability, crosslinkable materials were coated on sulfonated polyimide membrane and they were crosslinked at

A series of cross-linkable sulfonated poly(arylene ether ketone)s bearing carboxylic acid groups (C-SPAEKs) have been prepared for direct methanol fuel cells (DMFCs). The chemical structure of the cross-linkable copolymers was analyzed by 1 H NMR and 13 C NMR spectra. Cross-linked membranes were obt
## Abstract With a view towards direct methanol fuel cell applications, novel sulfonated poly(phenylene sulfide sulfone nitrile) (sPPSSfN) has been prepared and subsequently crosslinked by a FriedelβCraft reaction using 4,4β²βoxybis(benzoic acid) as a crosslinker to achieve lower water swelling and
