| Abstract: | 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 × 6 cm was developed by using the composite-type membrane of (Ce0.85Sm0.15)O2-15vol%MnFe2O4 and ferric stainless-steel separators. For the reformer module, high CH4 conversion and H2 selectivity of 96% and 89% were achieved, respectively. Based on energy analysis, it can be found that ΔG of partial oxidation of methane was effectively used for oxygen separation and heat compensation. The durability of the membrane was confirmed for 450 h. |
