Advanced Alkaline Membrane H2/Air Fuel Cell System with Novel Technique for Air CO2
The University of Delaware will build an electrochemical “pump,” based on a special membrane, to remove cell-damaging CO2 from ambient air before feeding it along with hydrogen into an HEMFC designed by the team. This method eliminates the need for vehicles using HEMFCs to carry an onboard oxygen supply or scrub carbon dioxide by other more expensive routes. The same principle could be applied to direct carbon capture from air for any system with a similar challenge. If successful, this electrochemical pump-HEMFC unit will meet performance, volume, and cost requirements for passenger vehicles.
The University of Delaware’s HEMFC system’s ability to operate on ambient air enables it to overcome the last major barrier for hydrogen-fueled transport applications based on HEM.
