## Abstract

Provided is a method for producing a hydrogen-containing gas, especially hydrogen for a fuel cell, by reforming a C5 or more hydrocarbon or oxygen-containing hydrocarbon that is liquid at ordinary temperature and pressure. This is a method for producing a hydrogen-containing gas, which comprises reforming a hydrocarbon or an oxygen-containing hydrocarbon having at least 5 carbon atoms and liquid at ordinary temperature and pressure, with a catalyst that contains Ni, Mg and Al and contains at least one noble metal element selected from Pt, Pd, Ir, Rh and Ru.

## Claims
