    • A methanol reforming catalyst that generates a reformed gas containing hydrogen by reforming methanol under the presence of oxygen and steam, comprises a catalytic component I containing Cu oxide and Zn oxide, and a catalytic component II containing metal oxide and one of Pt and Pd.Also, another methanol reforming catalyst comprises a catalytic component I containing Cu oxide and Zn oxide, a catalytic component IIA containing first metal oxide and a noble metal, and a catalytic component IIB containing second metal oxide and one of Pt and Pd. The second metal oxide forms an alloy more easily than the first metal oxide. The auto-thermal reforming process can be stably accelerated in the methanol reforming reaction using these catalysts. Also, there are provided a reformer, a reforming apparatus, and a fuel cell system employing these methanol catalysts. Since a heater or a reducing apparatus can be omitted in these apparatuses, etc., sizes of these apparatuses, etc. become small and thus these apparatuses, etc. are suitable for the installing into the mobile body.
    • 通过在氧气和蒸汽的存在下通过重整甲醇生成含氢气的重整气体的甲醇重整催化剂包含含有氧化Cu和氧化锌的催化组分I,以及含有金属氧化物和Pt和Pd之一的催化组分II。 另一种甲醇重整催化剂包含含有氧化铜和氧化锌的催化组分I,含有第一金属氧化物的催化组分IIA和贵金属,以及含有第二金属氧化物和Pt和Pd之一的催化组分IIB。 第二金属氧化物比第一金属氧化物更容易形成合金。 在使用这些催化剂的甲醇重整反应中可以稳定地加速自热重整过程。 此外,提供了一种重整器,重整装置和使用这些甲醇催化剂的燃料电池系统。 由于在这些装置等中可以省略加热器或还原装置,所以这些装置等的尺寸变小,因此这些装置等适合于安装在移动体中。
