Abstract: Disclosed is a hydrocarbon reforming method and a hydrocarbon reforming device which ensure high yield and prolonged lifetime of an oxygen-permeable membrane. In the hydrocarbon reforming method, a partial oxidation reforming reaction using oxygen isolated with an oxygen-permeable membrane and a steam reforming reaction are performed using a hydrocarbon as a starting material to produce a hydrogen-containing gas. In the method, the overheating of the oxygen-permeable membrane can be prevented by removing a Joule heat that is generated during the isolation of oxygen. The energy corresponding to a portion of the Joule heat which is absorbed for the increase in entropy associated with the partial oxidation reforming reaction is utilized as the heat to be adsorbed associated with the steam reforming reaction.

Abstract: [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, ΔG, 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 , ΔG of the partial oxidation reforming reaction is approximately ten times larger than ΔH, 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, TΔS, of the partial oxidation reaction itself and by steam reforming using the total energy change, ΔH.

Abstract: Disclosed is an electrochemical cell which uses a proton conductor as the electrolyte. The electrochemical cell has excellent stability especially to a gas containing carbon dioxide. Specifically disclosed is an electrochemical cell (20B) which uses a ceramic having a composition of SrZr0.5Ce0.4Y0.1O3-δ as a proton conductive electrolyte (21). As a cathode, an intermediate layer (22) which is a thin film of a proton conductor having a composition of SrCe0.95Yb0.05O3-δ is arranged on the electrolyte (21), and a porous platinum electrode (23c) is fixed thereon. A palladium electrode (23a) is used as an anode. In a cell (20A) having no intermediate layer (22), a high overvoltage near 600 mV occurs at a low current density of 70 mA/cm2. Meanwhile, in the cell (20B) having the intermediate layer (22), a low overvoltage about 170 mV occurs at a current density of 680 mA/cm2.
