Proton exchang e membranes e xhibiting a well-org anized structure were successfully prepared by a novel self-assembling technique using surface-charged latex nanoparticles as building blocks. The nanoparticles were synthesized in water by free-radical copolymerization. Free-standing membranes were obtained by casting the poly mer e mulsions followed by a cross-linking reaction. The acquired me...

A measurement system for current distribution mapping for a PEFC has been developed. The segmented anode is constructed so as to have high thermal conductivity in order to prevent the formation of large temperature gradients between the electrodes. The construction is therefore feasible for use at high current densities. Both segmented and unsegmented gas diffusion layers are used. The effect o...

A novel sulfonated polybenzimidazole/organoclay (Cloisite-30B) (SPBI/clay) nanocomposite membranes was successfully synthesized based on aromatic diacide (1) and diaminobenzidine. Nanocomposite membranes were fabricated using 1, 4-bis (hydroxymethyl) benzene (BHMB) as cross-linker, and Cloisite-30B organoclay as the pseudo cross-linker. The cross-linked SPBI/clay nanocomposite membranes were pr...

Abstract Enhancing the proton conductivity of exchange membranes (PEMs) is essential to expand applications membrane fuel cells (PEMFCs). Inspired by conduction mechanism bacteriorhodopsin, cucurbit[ n ]urils (CB[ ], where number glycoluril units, = 6, 7, or 8) are introduced into sulfonated poly(ether ether ketone) (SPEEK) matrix fabricate hybrid PEMs, employing a nature-inspired chemical engi...
