CA 2596688

This invention provides a catalyst material comprising a conductive material coated with a polynuclear complex molecule derived from at least two types of heteromonocyclic compounds and a catalyst metal coordinated to the coating layer of the polynuclear complex molecule, and a catalyst material comprising a conductive material coated with a polynuclear complex molecule derived from a heteromonocyclic compound and a catalyst metal, which is a composite of a noble metal and a transition metal, coordinated to the coating layer of the polynuclear complex molecule. Such catalyst material of the invention has excellent catalytic performance and serviceability as, for example, an electrode of fuel cells.

L~invention concerne un matériau catalytique caractérisé en ce que dans un matériau électroconducteur revêtu de molécules de complexe polynucléaire dérivées de deux types ou plus de composés hétéromonocycliques, un matériau catalytique est coordonné à la couche de revêtement comprenant les molécules de complexe polynucléaire ; ou un matériau catalytique caractérisé en ce que dans un matériau électroconducteur revêtu de molécules de complexe polynucléaire dérivées d~un composé hétéromonocyclique, un métal catalytique est coordonné, en tant que composite d~un métal noble et d~un métal de transition, à la couche de revêtement comprenant les molécules de complexe polynucléaire. Le matériau catalytique démontre d~excellentes caractéristiques catalytiques et peut être utilisé pratiquement en tant qu~une électrode d~une pile à combustible, ou similaire.
