[Objects] To provide a method and an apparatus for reforming a hydrocarbon with a prolonged life of an oxygen-permeable membrane and a high recovery rate. [Solutions] The oxygen-permeable membrane absorbs the free energy change, &Dgr;G, of a partial oxidation reforming reaction and then converts it into work for oxygen isolation and Joule heat, Q. Here, as seen in Table 1 and FIG. 1, &Dgr;G of the partial oxidation reforming reaction is approximately ten times larger than &Dgr;H, and further increases as the temperature increases. The generated Joule heat, Q, has to be removed at a high efficiency, and this removal process is achieved by returning a portion of the Joule heat to the system as the entropy change, T&Dgr;S, of the partial oxidation reaction itself and by steam reforming using the total energy change, &Dgr;H.
