ABSTRACT:
Disclosed herein are electrode composition material for a polymer electrolyte fuel cell and a process of preparing same. The electrode composition material includes agglomerates composed of catalyst-loading particles coated with or not coated with ion exchange resin having two particle distribution peaks. The electrode composition material having the two particle distribution peaks supplements the drawbacks of excessively fine particles and of excessively coarse particles and can obtain the excellent cell performance.
