NOVELTY - Catalyst ink composition for a fuel cell electrode, comprises: many electrically conductive support particles; a catalyst formed from a finely divided precious metal, where the catalyst is 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 drying.    USE - The catalyst ink composition is useful for the fabrication of the electrodes of a fuel cell, which is useful as a power source for electric vehicles.    ADVANTAGE - The catalyst ink composition: inhibits the formation of cracks in the electrode; reduces the occurrence of stress concentrations of the electrolyte membrane; optimizes the durability of the electrode; provides external reinforcement to the electrolyte membrane, thus enhancing the performance of the fuel cell; and requires less drying time, thus minimizing the manufacturing cost of the fuel cell.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) an electrode (6) for a fuel cell (2), comprising an ionomer matrix having many electrically conductive support particles supporting the catalyst formed from a finely divided precious metal, and a reinforcing material (which is substantially evenly distributed throughout the ionomer matrix, bridges across the electrically conductive support particles and is configured to distribute stresses on the electrode); and    (2) a method for fabricating the electrode for a fuel cell, comprising (i) providing a substrate for the electrode, (ii) providing the catalyst ink composition, (iii) depositing the catalyst ink composition onto the substrate and (iv) drying the catalyst ink to form the electrode for the fuel cell.    DESCRIPTION OF DRAWING(S) - The figure shows the schematic cross-sectional view of the fuel cell having electrodes formed from the catalyst ink composition.
