CATALYST FOR FUEL CELL ELECTRODE, PROCESS FOR PRODUCING CATALYST FOR FUEL CELL ELECTRODE, FILM-ELECTRODE ASSEMBLY, AND FUEL CELL

Document Type and Number:

WIPO Patent Application WO/2007/077972

Kind Code:

A1

Abstract:

A catalyst for fuel cell electrodes which is advantageous for inhibiting a carbon support, e.g., carbon nanotubes, from agglomerating and is advantageous for keeping three ingredients consisting of the carbon support, a catalyst ingredient, and an electrolyte ingredient in tight contact with one another; and a process for producing the catalyst for fuel cell electrodes. The catalyst for fuel cell electrodes comprises a carbon support having a Π-conjugated system (e.g., CNTs), an electrolyte ingredient having an aromatic ring, and a catalyst ingredient. In the process for producing the catalyst for fuel cell electrodes, a carbon support having a Π-conjugated system (e.g., CNTs), an electrolyte ingredient having an aromatic ring, and a catalyst ingredient are brought into contact with one another in a solvent. Thus, the carbon support can be modified with the electrolyte ingredient and the catalyst ingredient can be fixed to the support.
