    摘要： An electrode catalyst for a fuel cell, which has improved performance compared with conventional platinum alloy catalysts, a method for producing the electrode catalyst, and a polymer electrolyte fuel cell using the electrode catalyst are provided. The electrode catalyst for a fuel cell comprises a noble-metal-non-precious metal alloy that has a core-shell structure supported on a conductive carrier. The composition of the catalyst components of the shell is such that the amount of the noble metal is greater than or equal to the amount of the non-precious metal.

    摘要： A catalyst for purifying exhaust gases comprises a catalyst carrier made of potassium titanate and a noble metal loaded on the catalyst carrier. The catalyst carrier is substantially free from alumina. This catalyst can oxidize at least hydrocarbons in exhaust gases at a high catalytic activity even at low temperatures, and at the same time can suppress SO.sub.2 from converting into sulfates. This catalyst does not employ substance like alumina exhibiting solid acidity as a catalyst carrier. Further, this catalyst can be used for purifying exhaust gases from diesel engines to suppress particulates and sulfates from being emitted, and to improve conversions of hydrocarbons and carbon monoxide.
