NOVELTY - The reformer (100) has a catalyst reaction unit connected to a mixer (154) of a plasma reforming water shift part. A catalyst for promoting hydrogen is provided in an inner side. A heat transfer unit is utilized for producing steam, and is connected to one end of the catalyst reaction unit, where the end of the catalyst reaction unit collects heat. An electrode tip is combined in a gas injection nozzle, and is made of copper material in which nickel and hafnium are contained. The gas injection nozzle is made of Teflon (RTM: PTFE) material.    USE - High speed starting plasma reformer for a home fuel system in a home power generation unit having a solid oxide fuel cell (SOFC), molten carbonate fuel cell (MCFC), phosphoric acid fuel cell (PAFC), proton exchange membrane fuel cell (PEMFC), and an alkaline fuel cell (AFC), of a move mode vehicle (all claimed).    ADVANTAGE - The reformer provides fast reactivity, and improves the hydrogen productivity with high concentration. The generated plasma heat reaches the reaction temperature without utilizing an external heating source, and the necessary warm-up time is reduced in the reformer, so that efficiency of the reformer can be increased. The reformer can produce the hydrogen from different types of hydrocarbon class fuels by utilizing high energy of the plasma. The catalytic reaction allows the reformer to produce the hydrogen with high purity. The reformer is more compact, and is applicable to different fuel cells having operation characteristic in high temperature or low temperature. The reformer has excellent adaptability. The reformer reaches the necessary temperature within the time less than the existing reformer, so that the reformer can be applied in the mini-fuel cell of the portable vehicle.
