Abstract
In an electrochemical fuel cell, an electrode substrate has an in-plane nonuniform structure. The electrode substrate having an in-plane nonuniform structure enables controlled transport of reactant toward the electrocatalyst layer and controlled transport of reaction product away from the electrocatalyst layer.
