Abstract
A method for manufacturing a fuel cell electrode includes forming a first mixture by mixing a first cation exchange resin, a metal catalyst, and a first solvent, powderizing the first mixture to produce a first catalyst powder comprising the metal catalyst coated with the first cation exchange resin, forming a second mixture by mixing the first catalyst powder, a second cation exchange resin, and a second solvent, powderizing the second mixture to produce a catalyst powder having a core and two or more layers of shells and being coated with the second cation exchange resin, mixing the catalyst powder having the core and two or more layers of shells with a third solvent to produce a catalyst slurry, and coating, using the catalyst slurry, to produce an electrode.
