金属とからなるサーメットが用いられている。2. Description of the Related Art Conventional fuel reforming catalysts of this type include alumina (Al 2 O 3 ) and zirconia (ZrO 2 ).
A cermet made of ceramics such as Ni and Ru, Fe, Co, Pt and the like is used.

れている。In the conventional SOFC, the Ni-ZrO 2 cermet fuel electrode manufactured by coating and baking has a drawback that it has large polarization and poor long-term stability. Such a drawback is caused by the catalytic action of N.
It is believed that the i-structure is not optimally controlled, or that the structure is destroyed by Ni sintering at the battery operating temperature.

う欠点があった。However, the C / H by the conventional catalyst for fuel reforming is included, including the case of reforming the C / H fuel inside the conventional SOFC having the fuel electrode made of Ni-ZrO 2 cermet.
In reforming the H fuel, it is desired that the ratio of steam to the carbon amount of the C / H fuel (hereinafter referred to as "S / C ratio") be as low as possible. However, there is a drawback that carbon is deposited on the upper surface of the catalyst and the catalytic active sites are covered therewith to lower the catalytic activity.
