英文摘要	currently, h-2 production techniques for application to proton exchange membrane fuel cells (pemfc) are intensively investigated, aiming to realize a clean hydrogen society. due to the limitation by the thermodynamics of methane steam reforming (msr), multi-reactions and multi-steps should be performed before the generated h-2-rich gas could be delivered to pemfc, which inevitably increases the cost of h-2. however, using a thermodynamic shifting membrane reformer, h-2 could be produced compactly from msr, provided that the catalyst showed high performance for msr reaction and membrane efficiently removed h-2 from the reaction zone. we presented here a pd-based membrane reformer for msr reaction. in contrast with previous reports, nickel-based catalyst pre-reduced at high temperature was applied in this work, as well as high performance pd-based membrane. the performances of the membrane reformer in terms of h-2 production capacity were also widely investigated. it was found that combination of an active catalyst for msr and a h-2 ultra-permeable pd membrane obtained high flux of h-2 across the membrane and recovery rate of h-2 in the membrane reformer. for instance, 98.8% methane conversion, over 97.0% selectivity to co2 and over 95.0% recovery rate of h-2 were obtained under mild working conditions. simultaneously, the hydrogen flux across the membrane reached 18.6 m(3)/(m(2) h), and pd-based pure h2 production capacity significantly increased and reached around 387.5 m(3)/(kg(pd) h) in membrane reformer. further work on stability investigation may develop an efficient on-site route of h-2 production process for application to on-site power generation using pemfc.
