Abstract: A fuel reforming apparatus in constructed with a main body including a first pipe and a second pipe disposed in the first pipe and a heat source installed in the second pipe and adapted to generate thermal energy in the second pipe. A reforming reaction unit is formed by filling a reforming catalyst in a space defined between the first and second pipes and is adapted to generate a reformed gas containing hydrogen through a reforming reaction of the fuel. A housing encloses the main body and allows a combustion gas generated from the heat source to flow along an outer circumference of the reforming reaction unit.

Abstract: Disclosed is a fuel cell system which includes a generator, a reformer generating a reformed gas by reforming a gaseous fuel and water and supplying the reformed gas to the generator. A fuel tank stores the gaseous fuel in a liquid state by compressing the gaseous fuel and supplying the gaseous fuel to the reformer. A water supply device supplies the water to the reformer. The water supply device includes a container connected to the fuel tank and the reformer and contains the water and the gaseous fuel with a pressure. A separation layer is formed on the surface of the water in the container for blocking a contact of the gaseous fuel with the water.
