چکیده

4,5-Dicyano-1H-[1,2,3]-Triazole (DCTz) exhibits a very low proton affinity. This makes it a possible water replacement for proton transport in high temperature polymer electrolyte membranes. A detailed investigation is carried out to define various physical properties as well as the proton transfer characteristics of DCTz. Thermogravimetric analysis showed that DCTz as well as DCTz salts are thermally stable at high temperature (> 100°C). H NMR spectra reveal proton exchange in DCTz solutions. The NMR spectroscopy reveals the dependence of proton transport on concentration, temperature and the presence of excess protons added as acid dopants.

Studies on the SPEEK membrane with low degree of sulfonation as a stable proton exchange membrane for fuel cell applications

Sulfonated poly (ether ether ketone) (SPEEK) with a low degree of sulfonation (DS = 40%) was prepared for proton exchange membrane fuel cells (PEMFC). Poly (ether ether ketone) (PEEK) was sulfonated in concentrated H2SO4 under N2 atmosphere and characterized by the hydrogen nuclear magnetic resonance (H-NMR) technique. After preparation of the SPEEK polymer, the obtained polymer was dissolved i...

Promotion of proton conduction in polymer electrolyte membranes by 1H-1,2,3-triazole.

We report 1H-1,2,3-triazole as an active group to dramatically enhance proton conduction in a polymer electrolyte membrane (PEM). The conductivities of a poly(4-vinyl-1H-1,2,3-triazole) membrane without any acidic dopants are about 105 times greater than those of poly(4-vinylimidazole) in dry air at 50-150 degrees C. Polymers with groups promoting proton conduction attached to the backbone have...
