    Abstract: 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.

    Abstract: 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.

    Abstract: 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

    Abstract: A power system of the invention includes fuel cells and a fuel gas generation system that generates a fuel gas to be supplied to the fuel cells. At the time of stopping supply of hydrogen, the fuel gas generation system selectively uses a stop process that replaces hydrogen in a hydrogen separator unit with the air for removal of hydrogen and a pause process that allows hydrogen to remain in the hydrogen separator unit. The stop process is selected when the fuel gas generation system stops the supply of hydrogen for a long time period. The pause process is selected when the fuel gas generation system temporarily stops the supply of hydrogen. The arrangement of the invention desirably shortens a restart time of the fuel gas generation system and reduces a potential energy loss.
