    摘要： An electrode catalyst for a fuel cell includes a conductive support, and catalytic particles loaded on the conductive support. The catalytic particles include platinum and a base metal being on the lower end of the electrochemical series with respect to platinum. The number of the atoms of the base metal, forming metallic oxides without alloying with the platinum, is less than 5 atomic % of the number of the atoms of the platinum on a surface of the catalytic particles. The electrode catalyst is produced by loading the platinum and base metal on the conductive support, alloying the platinum and base metal thereon by a heat treatment, thereby making the catalytic particles, and removing metallic oxides from a surface of the catalytic particles. The electrode catalyst is less expensive comparatively, exhibits high catalytic activities, and hardly lowers the battery performance of fuel cells.

    摘要： A fuel cell electrode which can improve the catalyst utilization rate by having the catalyst component supported at a high density and high dispersion is provided. An aqueous solution containing chloroplatinic acid and aniline is prepared. For an electrode diffusion layer, a carbon paper is soaked in a Teflon® dispersion solution and then dried. One side of the electrode diffusion layer is placed in contact with the liquid surface of the solution, and a counter-electrode made of graphite is provided in the solution. A constant electrical current is applied between them, with the electrode diffusion layer side as the positive electrode. As a result, aniline is oxidatively polymerized by electrochemical means, and a uniform layer of platinum-containing polyaniline is formed on the electrode diffusion layer surface. The platinum in the polyaniline is reduced, and this is washed with pure water and dried to make the electrode. Two of these electrodes, with the catalytic layer of the platinum-containing polyaniline on the inside, are placed against both sides of Nafion® to create a small fuel cell.
