Abstract
A method for enriching the oxygen fed to a fuel cell cathode intake comprises receiving at the cathode intake an oxidant from the air, storing oxygen in an adsorber coupled to the cathode intake, and adding the stored oxygen from the adsorber to the oxidant at the cathode intake during high current density operation. A fuel cell system comprises a membrane, an anode on one side of the membrane, and a cathode, coupled to a blocking member, on a second side of the membrane. The cathode comprising an intake configured to allow an oxidant to flow through the cathode, and an outlet configured to discharge unreacted oxygen from the cathode, an adsorber, coupled to the blocking member, configured to store oxygen for adding to the oxidant flowing through the cathode intake during high current density operation.
