Abstract

A small cylindrical reformer having at least a combustion reaction unit and a fuel-converting catalytic reaction unit wherein the combustion reaction unit and the fuel-converting catalytic reaction unit are structured as six cylindrical pipes to realize optimal heat exchange efficiently, a route supplying a water gas shift reformate to a preferential oxidation reactor and a route supplying feed and water into reforming reaction parts from the feed/water inlet overlap each other at a lower portion of the reformer so as to increase heat transfer efficiency, and a preferential oxidation reactor provided outside the fuel-converting catalytic reaction unit to decrease the concentration of carbon monoxide in the water gas shift reformate to a predetermined level or lower and increase heat transfer efficiency with an air/fuel preheating passage communicating with the air/fuel inlet.
