摘要：
This paper describes the fabrication of a novel hydrogen production system based on an oxygen permeable membrane and its methane reforming properties. The planar-type membrane reformer module with dimensions of 6 cm x 6 cm was developed by using the composite-type membrane of (Ce(0.85)Sm(0.15))O(2)-15vo1%MnFe(2)O(4) and ferric stainless-steel separators. For the reformer module, high CH(4) conversion and H(2) selectivity of 96% and 89% were achieved, respectively. Based on energy analysis, it can be found that Delta G of partial oxidation of methane was effectively used for oxygen separation and heat compensation. The durability of the membrane was confirmed for 450 h.
