HYDROGEN GENERATION APPARATUS FOR FUEL CELL TO PRODUCE HYDROGEN-RICH GAS BY VAPOR MODIFICATION OF HYDROCARBON-BASED FUEL GAS, IMPROVED IN HEAT EFFICIENCY AND SIMPLIFIED IN STRUCTURE

摘要

PURPOSE: Provided is a hydrogen generation apparatus for a fuel cell to produce a hydrogen-rich gas by the vapor modification of a hydrocarbon-based fuel gas which is improved in heat efficiency and needs no external heat exchanger. CONSTITUTION: The hydrogen generation apparatus(1) comprises a modification pipe(3) where a catalyst layer(2) is formed by charging a modification catalyst between a standing upright inner pipe(20) and a polygonal or waveform outer pipe(21) surrounding the standing upright inner pipe; an outermost pipe(22) inscribed with the each stationary point of the polygonal or waveform outer pipe; and a modification gas channel which is formed between the outer pipe and the outermost pipe. The modification catalyst reacts with a fuel containing an organic compound having a hydrogen atom in molecule with water to modify it into a hydrogen-rich gas.
