Abstract
Improved catalyst layers for use in fuel cell membrane electrode assemblies, and methods for making such catalyst layers, are provided. Catalyst layers can comprise structured units of catalyst, catalyst support, and ionomer. The structured units can provide for more efficient electrical energy production and/or increased lifespan of fuel cells utilizing such membrane electrode assemblies. Catalyst layers can be directly deposited on exchange membranes, such as proton exchange membranes.
