摘要： A hydrogen-permeable membrane includes a permeable layer which has a function of making hydrogen permeate therethrough, and a catalyst layer which acts as a catalyst for promoting permeation of the hydrogen in the permeable layer. An area of the catalyst layer which contacts gas is larger than an area of the permeable layer.

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： 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： 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.
