Abstract

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.
