NOVELTY - A fuel reforming apparatus comprises: a fuel reforming reactor (10) including a catalyst (14) or a stack of the catalyst, which is present in the form of a disk having through-hole, mounted in the reactor; an igniter (26) for generating an electric spark at an interior of the through-hole; and a gas supply line for supplying fuel (31) and air (32) to the interior of the through-hole.    USE - As a fuel reforming apparatus (claimed) for performing partial oxidation reforming reaction of fuel cells e.g. household, portable and car fuel cells.    ADVANTAGE - The fuel reforming apparatus containing catalyst for partial oxidation reforming reaction of fuel in the form of disk having through-hole, allows the progress the partial oxidation reforming reaction of fuel smoothly, while minimizing the variation of gas pressure and preventing hot spots in the catalyst; improves the efficiency of fuel reforming; and simplifies the fuel reforming reactor; as compared to the prior art catalyst, presence in the form of a powders, or pellet or monolith and are associated with pressure drop, and difficulty on controlling the heat of reaction, respectively. The catalyst provides an efficient control and use of heat of reaction, and provides a simple on-off operation, reduction of starting time and a stable operational condition are obtained, using LPG (propane) or LNG (methane) as fuel of the fuel reforming system. As the reforming gas is used directly for combustion reaction as well as partial oxidation reforming reaction, and the combustion heat increases the temperature of the catalyst by burning the reforming fuel in the through-hole of the catalyst; the starting time is shortened and thus the operation of the reforming system is possible in 1 - 2 minutes. Additionally, the apparatus easily allows the combustion reaction to proceed at room temperature by generating the spark at the interior of the stack of catalysts using the igniter. Since the ignition is accomplished by using the electric accumulation device, an electric supply from the outside is not necessary. This further greatly shortens the start-up time, while using the minimum amount of electricity. As the reforming gas is used directly for combustion reaction and partial oxidation reforming reaction, the apparatus is suitable for a system or equipment required for a small-sized apparatus, and further simplifies the structure of the fuel reforming reactor.
