英文摘要: A multilayer composite membrane was prepared by reinforcing sulfonated polysulfone (SPSU) with porous polytetrafluoroethylene (PTFE), and adding Pt/SiO2-Nafion (R) membranes on both sides of the SPSU/PTFE membrane to self-humidify and protect the inside membrane. The ex situ Fenton test and open circuit voltage (OCV) accelerated test show that the composite membrane has better stability than the initial membrane because of the protection of the outside Pt/SiO2-Nafion layers. The composite membrane has similar performance to that of NRE-212 under the fully humidified condition and better performance than NRE-212 without humidifying. The self-humidifying membrane shows great potential for use in low humidifying conditions. Copyright (C) 2008 John Wiley & Sons, Ltd.
