Beschreibung
Zusammenfassung:	There is disclosed a membrane reactor 100 for a shift reaction including a selectively permeable membrane 3 having an H2-selective permeation ability and a catalyst 4 which promotes a chemical reaction, the selectively permeable membrane 3 is a Pd membrane or a Pd alloy membrane, the catalyst 4 is a precious metal catalyst, and the selectively permeable membrane preferably has a thickness of 20 mum or less. The membrane reactor 100 for the shift reaction simultaneously performs inhibition of a methanation reaction and progression of a shift reaction while preventing deterioration of a thinly formed selectively permeable membrane, whereby hydrogen can efficiently be collected.
