PROBLEM TO BE SOLVED: To provide a pressurized reforming device capable of giving high reforming efficiency in a pressurized state without raising operation temperature of a plate reformer. SOLUTION: This device comprises a reforming chamber 12 filled with reforming catalysts 3 and supplied with hydrocarbon gas 2 including steam, a combustion chamber 14 separated from the reforming chamber by a highly heat-conductive thin plate 14a for burning fuel gas 1, and a permeation chamber 16 separated from the reforming chamber by a hydrogen separating film 16a and supplied with anode exhaust gas 11 coming out of a fuel cell. The flow rate of the anode exhaust gas supplied to the permeation chamber is set up to cause hydrogen partial pressure in the reforming chamber to be always higher than that in the permeation chamber, and gas combing out of the permeation chamber is joinned with gas coming out of the reforming chamber and supplied to the anode side of the fuel cell. |
