CATALYTIC ELECTRODE FOR FUEL CELL, FUEL CELL, CATALYST BEARING PARTICLE FOR FUEL CELL AND PROCESS FOR PRODUCING THE CATALYTIC ELECTRODE FOR FUEL CELL

摘要

Catalytic electrodes for fuel cell (102, 108) comprise conductive substrates (104, 110) and, superimposed on the substrates (104, 110), catalyst layers (106, 112). These catalyst layers (106, 112) comprise carbon particles (401) bearing catalytic substance (405) which have an average particle diameter of given range and solid polymeric electrolyte material (403) mixed with the carbon particles (401). These carbon particles (401) comprise carbon nanohorn aggregate (401) composed of multiple carbon nanohorns (407) aggregated spherically. This carbon nanohorn aggregate (407) bears the above catalytic substance (405).
