ABSTRACT:
A catalyst ink composition for a fuel cell electrode is provided. The catalyst ink composition includes a plurality of electrically conductive support particles; a catalyst formed from a finely divided precious metal, the catalyst supported by the conductive support particles; an ionomer; at least one solvent; and a reinforcing material configured to bridge and distribute stresses across the electrically conductive support particles of the ink composition upon a drying thereof. An electrode for a fuel cell and a method of fabricating the electrode with the catalyst ink composition are also provided.
