Superfast proton diffusion achieved in a plasma-polymerized fuel-cell membrane

Peterson, Vanessa K; Corr, Cormac; Boswell, Roderick; Zunbeltz, Izaola; Kearley, Gordon


We measure superfast proton diffusion in a proton-exchange membrane (PEM) produced by plasma polymerization. The proton self-diffusion is measured in water-saturated PEMs from the proton autocorrelation function obtained from quasielastic neutron scattering (QENS). 41(3)% of protons in the plasma-produced membrane diffuse at a rate that is an order of magnitude faster than that measured in the commercially available membrane, Nafion, and this is achieved in low hydration conditions. Both...[Show more]
