NOVELTY - The fuel reformer comprises a porous media to vaporize the liquid fuel flowed in a through pipe, a reactor, a fuel powder, which is placed on the porous media, an inlet hole formed on a side of the reactor, and a screen part. The reactor disperses the liquid fuel and supplies the porous media. The liquid fuel is hydrocarbon. The screen part covers the porous media, is connected to the pipe, and contains through-holes. The fuel reformer further comprises a jaw protruded in an edge portion, an electric heater surrounding the porous media, and a snap ring.    USE - The fuel reformer is useful for producing hydrogen from the liquid fuel.    ADVANTAGE - The fuel reformer produces hydrogen in an economical manner.    DETAILED DESCRIPTION - The fuel reformer comprises a porous media to vaporize the liquid fuel flowed in a through pipe, a reactor, a fuel powder, which is placed on the porous media, an inlet hole formed on a side of the reactor, and a screen part. The reactor disperses the liquid fuel and supplies the porous media. The liquid fuel is hydrocarbon. The screen part covers the porous media, is connected to the pipe, and contains through-holes. The fuel reformer further comprises a jaw protruded in an edge portion, an electric heater surrounding the porous media, a snap ring inserted into a groove formed in the inner wall of the reactor, a side jacket forming a supplied fluid path, an inlet hole equipped within the side jacket, and a connection pipe surrounding the reactor containing a catalytic bed in an inside. The jaw supports an upper end inner wall of the reactor, and forms the predetermined gap between the screen part and the through pipe. The size of the holes is enlarged from the part facing to the through pipe. The porous media has a porosity of 35-65% and a particle size of 20-300 mm. The snap ring covers and supports a rear side of the porous media. An outer periphery of the reactor is surrounded by air and steam. The catalyst bed produces hydrogen, which is introduced at the rear end of the reactor, and absorbs the heat, where the liquid fuel is supplied the to pipe.
