摘要： A hydrogen generation device includes a catalyst; a sulfur-trap member; a soot-trap member; a pair of reformers; and a control portion. In each reformer, a reforming reaction is carried out to generate hydrogen-containing gas using gasoline and cathode off-gas on the catalyst, and an exothermic reaction is carried out to heat the catalyst using anode off-gas and air. The control portion executes a control such that the reactant and the exothermic material are alternately supplied to each reformer, whereby the reforming reaction and the exothermic reaction are alternately carried out in each reformer. A fuel cell system includes the hydrogen generation device.

摘要： The invention provides an electrolyte membrane that allows an operating temperature of a solid polymer membrane fuel cell to be raised and an operating temperature of a solid oxide fuel cell to be lowered. This electrolyte membrane can be used in a fuel cell that is operable in an intermediate temperature range. The invention also provides a fuel cell using such an electrolyte membrane. The electrolyte membrane has a hydrated electrolyte layer, and dense layers made of a hydrogen permeable material that are formed on both sides of this electrolyte layer. Both sides of the electrolyte membrane are coated with dense layers. Consequently, evaporation of moisture contained in the electrolyte layer is suppressed, and increase in the resistance of the membrane is inhibited. As a result, the range of the operating temperature of the fuel cell can be enlarged.

摘要： Fuel cells 100 of the invention are operable at a temperature of about 500° C. The unit cell has a solid oxide electrolyte layer formed on a hydrogen separable metal layer. An anode has a catalyst supported thereon to accelerate a reforming reaction of methane. A fuel gas is produced by reforming a hydrocarbon-containing material in a reformer 20. Setting a lower reaction temperature enables production of the fuel gas containing both methane and hydrogen. In the fuel cells 100 receiving a supply of the fuel gas, the reforming reaction of methane contained in the fuel gas proceeds simultaneously with consumption of hydrogen contained in the fuel gas. This methane reforming reaction is endothermic to absorb heat produced in the process of power generation and thereby equalizes the operation temperature of the fuel cells 100.

摘要： The present invention has as an object to produce a thinner electrolyte layer in a solid oxide type fuel cell. In a solid oxide type fuel cell, a solid oxide electrolyte layer 110 is grown on the surface of a hydrogen-permeable metal layer 120. A structure is provided for preventing interlayer separation of the hydrogen-permeable metal layer 120 and the electrolyte layer 110 due to expansion of the hydrogen-permeable metal layer 120 during permeation of hydrogen. As the separation preventing mechanism, there can be employed a structure that prevents expansion of the hydrogen-permeable metal layer 120, or a structure wherein the electrolyte layer is divided to ameliorate stress during expansion. By so doing, the electrolyte layer can be thinned sufficiently.
