摘要: A multiply-fluorinated cobalt phthalocyanine (CoFPC) was prepared, which could reversibly interact with oxygen. CoFPC introduced into the hydrophobic perfluoroethylene-backbone domain of Nafion membrane. The localization did not reduce high proton conductivity (10−2–10−3 S cm−1) ascribed to hydrophilic channel Nafion. oxygen permeability through CoFPC/Nafion membrane higher than nitrogen and that pristine membrane, significantly enhanced at lower upstream pressure. permselectivity versus increased beyond 20 content in coated on a glassy carbon modified Pt/C catalyst. electrochemical reduction current suggested efficiently supplied Copyright © 2009 John Wiley & Sons, Ltd.
