Zusammenfassung:	PROBLEM TO BE SOLVED: To make a CO2 separator simple, inexpensive and compact in a compact fuel cell power generation system in which gas production processes such as modification of material or CO conversion is performed under pressure to obtain H2/CO2 mixture gas, CO2 is removed from the H2/CO2 mixture gas by a CO2 separator to produce high pressure/high concentration hydrogen, and the hydrogen thus produced is supplied for fuel cell power generation under low pressure (normal pressure).SOLUTION: A hydrophilic porous thin film 18 is provided on the surface of a porous support tube to apply CO2 absorption/permeation function to the porous support tube. A reaction process for gas producing is performed under pressure, and CO2 is separated by utilizing the differential pressure between the material gas side and the CO2 permeate side. Thus, CO2 can be separated with a simple and inexpensive way.
