    摘要: A reformer (8) reforms hydrocarbon fuel and generates reformate gas. A first carbon monoxide oxidizer (1) and second carbon monoxide oxidizer (2) disposed in series decrease the carbon monoxide concentration of the reformate gas by a prefential oxidation. The air for the preferential oxidation is supplied to the carbon monoxide oxidizer (1, 2) from a compressor (9). The reformer (8) consumes the water heated by the reaction heat of the first carbon monoxide oxidizer (1). The water amount supplied for the reformer (8) increases as a fuel reforming requirement of the reformer (8) increases. When the fuel reforming requirement increases, the water heating capability of the first carbon monoxide oxidizer (1) is enhanced with a sufficient response by increasing the proportion of air supplied to the first carbon monoxide oxidizer (1).

    摘要: A bulk exchange-spring magnet 12, a method of producing the same, and a device 20 incorporating the bulk exchange-spring magnet are disclosed. The magnet includes magnet powders 10 having hard and soft phases, and boron and oxygen atoms which cohere in boundary areas 16 between grains 14 of the densified magnet powders 10. In a production method, the magnet powders 10 are compacted so as to incorporate boron and oxygen atoms into the boundary areas 16 and are heated under a compacted state of the magnet powders at varying operating temperatures for a given time period. This results in formation of a highly densified magnet at a lower potential operating temperature for a shorter time period without the grain growth. The device 20 includes the bulk exchange-spring magnet 12 containing the boron and oxygen atoms cohering between the grains of the densified magnet powders.

    摘要: A gas diffusion layer for a fuel cell includes a conductive microparticle layer and a base material layer. The conductive microparticle layer is formed with first pores of no less than 0.5 μm and no more than 50 μm and second pores of no less than 0.05 μm and less than 0.5 μm. Pores are also formed in the base material layer. A total volume of the second pores is no less than 50% and less than 100% of a total volume of all of the pores in the conductive microparticle layer. By properly setting a pore size D1 of pores having a maximum volume ratio from among the first pores, water passages are formed in the first pores separately from gas passages formed in the second pores.
