Fuel cell system with carbon dioxide removal
A recently granted patent (Publication Number: US11909082B2) discloses a fuel cell system that includes a fuel cell stack with fuel and air electrodes, a fuel receiving unit, and multiple fluid pathways for fuel exhaust. The system also features a carbon processing unit to remove carbon dioxide from the exhaust and an air combination unit to mix the exhaust with air before providing it to the air electrodes of the fuel cell stack. The patent claims also detail the inclusion of a controller to regulate the amount of exhaust sent to the carbon processing unit based on the system's operational state or CO2 demand.
Furthermore, the patent describes additional components such as a heater in the air combination unit to react with hydrogen, an exhaust cooling component in the carbon processing unit to extract water, and multiple outlet pathways for exporting the separated CO2 for various predetermined uses. The system also includes a fan or blower controlled by the controller to manage the amount of exhaust sent to the carbon processing unit, showcasing a comprehensive and efficient design for carbon dioxide removal in fuel cell systems.
