摘要: Abstract An ultra-thin, free-standing proton-conductive membrane of Nafion ® /Phosphosilicate/Nafion (NPN) with a sandwich structure has been prepared. The NPN thickness 960 nm shows extremely low methanol permeability 1 × 10 −8 cm 2 s −1 , and area specific resistance (ASR) smaller than 0.2 Ω cm .
