| 英文摘要 | with an aim to operate the proton exchange membrane fuel cells (pemfcs) with dry reactants, an inorganic/organic self-humidifying membrane based on sulfonated polyether ether ketone (speek) hybrid with cs2.5h0.5pw12o40 supported pt catalyst (pt-cs2.5 catalyst) has been investigated. the pt-cs2.5 catalysts incorporated in the speek matrix provide the site for catalytic recombination of permeable h-2 and o-2 to form water, and meanwhile avoid short circuit through the whole membrane due to the insulated property of cs2.5h0.5pw12o40 support. furthermore, the pt-cs2.5 catalyst can adsorb the water and transfer proton inside the membrane for its hygroscopic and proton-conductive properties. the structure of the speek/pt-cs2.5 composite membrane was characterized by xrd, ft-ir, sem and eds. comparison of the physicochemical and electrochemical properties, such as ion exchange capacity (iec), water uptake and proton conductivity between the plain speek and speek/pt-cs2.5 composite membrane were investigated. additive stability measurements indicated that the pt-cs2.5 catalyst showed improved stability in the speek matrix compared to the pta particle in the speek matrix. single cell tests employing the speek/pt-cs2.5 self-humidifying membrane and the plain speek membrane under wet or dry operation conditions and primary 100 h fuel cell stability measurement were also conducted in the present study.
