FILM-ELECTRODE UNIT FOR POLYELECTROLYTE FUEL CELL, METHOD FOR MAKING THE SAME, AND INK FOR MAKING THE SAME

摘要

PROBLEM TO BE SOLVED: To furthermore improve the structure of a reaction layer including electrode catalyst so as to furthermore enhance the output power of a fuel cell at low current density. SOLUTION: A film-electrode unit which comprises a polyelectrolyte-film having a first and a second surface wherein both surfaces are in contact with porous reaction layers and gas partition layers, and wherein one of the two reaction layers includes noble metal as black powder, in the film-electrode unit for a polyelectrolyte-fuel cell where the reaction layers include noble metal catalyst carried on carbon and ionomers.
