Abstract
A reformer for a fuel cell system has at least a dual pipe configuration that forms independent spaces through which fuel containing hydrogen passes. The reformer includes a first reaction assembly for generating heat energy by an oxidation reaction of the fuel and a second reaction assembly for generating hydrogen gas from the fuel through a reforming reaction using the heat energy. The reformer further includes a first pipe, and a second pipe having a circumference significantly less than a circumference of the first pipe to thereby allow for positioning of the second pipe within the first pipe. An oxidation catalyst layer is formed in the second pipe, and a reforming catalyst layer is formed between the first pipe and the second pipe.
