英文摘要	a novel multifunctional catalyst cs(x)h(3-x)pw(12)o(40)/ceo(2) was prepared to mitigate the free radical attack to membranes in fuel cell environment. cs(x)h(3-x)pw(12)o(40)/ceo(2) nanoparticles synthesized by solution-based hydrothermal method and two-step impregnation method were dispersed uniformly into the nafion (r) resin, and then the composite membrane was prepared using solution-cast method. the particles prepared were characterized by x-ray powder diffraction (xrd), tem and ft-ir to evaluate the crystallite size, distribution of the nanopaticles and the crystal structure. the membrane degradation was investigated via ex situ fenton test and in situ open circuit voltage (ocv) accelerated test. in the durability tests, the fluoride emission rate (fer) reduced nearly one order of magnitude by adding cs(x)h(3-x)pw(12)o(40)/ceo(2) nanoparticles into the nafion membrane, suggesting that cs(x)h(3-x)pw(12)o(40)/ceo(2) catalyst has a promising application to greatly improve the proton exchange membrane (pem) durability.
