Patents Assigned to FuelCell Energy, Inc. Patent number: 11909082 Carbon dioxide production from carbonate fuel cells
Abstract: A fuel cell system includes a fuel cell stack having a plurality of fuel cells that each contain a plurality of fuel electrodes and air electrodes. The system includes a fuel receiving unit connected to the fuel cell stack, which receives a hydrocarbon fuel from a fuel supply. The system includes a fuel exhaust processing unit fluidly coupled to the fuel cell stack by a slip stream, where the fuel exhaust processing unit processes fuel exhaust from the fuel cell stack, and the slip stream is fluidly connected to an exhaust stream flowing from the fuel cell stack. The fuel processing unit removes a first portion of carbon dioxide (CO2) from fuel exhaust within the slip stream, outputs the first portion of CO2 in a first stream, and outputs a second portion of CO2 remaining from the fuel exhaust in the slip stream into a second stream, which includes hydrogen.
