摘要： When the hydrogen separating membrane is in a low temperature condition, a lean bus operation is carried out in a reformer in order to conduct warm-up while suppressing generation of hydrogen. At the timing t1 where the temperature of the hydrogen separator membrane has reached a temperature at which hydrogen embrittlement does not occur, reforming is initiated. In such a condition, oxygen is supplied to hydrogen which is permeated through the hydrogen separator membrane for burning the hydrogen, so as to further facilitate the warm-up. At the timing t2 where the temperature has reached an operation temperature, the supply of oxygen in a purge side is stopped so as to stop the burning of hydrogen, and an operation mode is shifted to a normal operation.

摘要： A hydrogen extraction unit has reformed gas flow channel plates, hydrogen separation plates, and purge gas flow channel plates, which are designed as thin metal plate members. The hydrogen extraction unit is constructed by laminating these thin plate members and then bonding them together by diffusion bonding. Each of reformed gas flow channel holes formed in the reformed gas flow channel plates constitutes a flow channel for reformed gas together with a correspondingly adjacent one of the hydrogen separation plates. Each of purge gas flow channel holes formed in the purge gas flow channel plates constitutes, together with a correspondingly adjacent one of the hydrogen separation plates, a flow channel for purge gas with which hydrogen extracted from reformed gas is mixed.

摘要： A hydrogen separation filter includes a plurality of hydrogen extraction layers, a plurality of separation layers with hydrogen separation films, and a plurality of reformed gas layers, which are laid one upon another in the sequence of the extraction layer, the separation layer, the reformed gas layer, and the separation layer to form a laminate structure. The respective layers are composed of porous ceramic material to ensure the required strength. The direction of the gas flow in the reformed gas layers and that in the extraction layers are respectively fixed to simplify the gas intake and discharge structure. The hydrogen separation filter is covered with a casing via a cushioning member to ensure the sufficient strength and the required sealing properties. A methanation catalyst that accelerates methanation of carbon monoxide is carried on either the separation layer or the extraction layer. This arrangement effectively relieves the adverse effects of contamination of resulting hydrogen with carbon monoxide, due to a pinhole or a partial damage of the layers.

摘要： The technique of the present invention enhances the separation efficiency and the production efficiency of hydrogen in a hydrogen production system for fuel cells, while reducing the size of the whole fuel gas production system. In the fuel gas production system of the present invention, a hydrocarbon compound is subjected to multi-step chemical processes including a reforming reaction, a shift reaction, and a CO oxidation to give a hydrogen-rich fuel gas. Gaseous hydrogen produced through the reforming reaction is separated by a hydrogen separation membrane having selective permeability to hydrogen. The residual gas after the separation of hydrogen has a low hydrogen partial pressure and undergoes the shift reaction at the accelerated rate. The hydrogen-rich processed gas obtained through the shift reaction and the CO oxidation joins with the separated hydrogen and is supplied to fuel cells. A purge gas for carrying out the hydrogen is introduced into a separation unit of hydrogen, in order to lower the hydrogen partial pressure and thereby enhance the separation efficiency of hydrogen. The residual gas after the separation of hydrogen undergoes combustion and is subsequently used as the purge gas

摘要： For a reforming device that generates fuel gas for fuel cells by decomposing hydrocarbon compounds such as natural gas and then using a hydrogen separation composite to selectively transmit hydrogen, a hydrogen separation composite having the following structure is used. A porous support medium made of ceramics, etc. is formed, and a hydrogen separation metal is supported in the pores so as to fill the inside of the support medium. It is also possible to support a reforming catalyst. By doing this, it is possible to increase the area at which the hydrogen separation metal contacts gas, so the hydrogen transmission performance is increased. Furthermore, to prevent raw material gas leaks due to pin holes, high pressure gas is supplied to the hydrogen extraction side, and the total pressure is made higher than the pressure on the raw material gas supply side without making the hydrogen partial pressure higher. By using these means, it is possible to increase the hydrogen separation performance for the reforming device and to make the device more compact.

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.

摘要： The manufacturing method of the invention is applied to manufacture a unit fuel cell 20, which has a hydrogen-permeable metal layer 22 of a hydrogen-permeable metal and an electrolyte layer 21 that is located on the hydrogen-permeable metal layer 22 and has proton conductivity. The method first forms the electrolyte layer 21 on the hydrogen-permeable metal layer 22, and subsequently forms an electrically conductive cathode 24 on the electrolyte layer 21 to block off an electrical connection between the cathode 24 and the hydrogen-permeable metal layer 22. The method releases Pd toward the electrolyte layer 21 in a direction substantially perpendicular to the electrolyte layer 21 to form a Pd layer as the cathode 24 that is thinner than the electrolyte layer 21. This arrangement of the invention effective prevents a potential short circuit, for example, between the cathode and the hydrogen-permeable metal layer, in the fuel cell, due to pores present in the electrolyte layer.

摘要： A fuel cell of the invention has a hydrogen permeable metal layer, which is formed on a plane of an electrolyte layer that has proton conductivity and includes a hydrogen permeable metal. The fuel cell includes a higher temperature zone and a lower temperature zone that has a lower temperature than the higher temperature zone.
