The graphene-based layer is disposed between the cathode catalyst layer and the electrolyte membrane layer and/or the anode catalyst layer and the electrolyte membrane layer. The graphene-based layer is configured to suppress crossover gases and metallic cation exchange to enhance performance and durability of the electrochemical cell.",
