Title: System for capturing CO2 from a fuel cell

Abstract

A carbon dioxide capture system for capturing carbon dioxide from an exhaust stream. The system may include a fuel cell configured to output a first exhaust stream comprising carbon dioxide and water. The system may further include an electrolyzer cell configured to receive a first portion of the first exhaust stream and output a second exhaust stream comprising oxygen and carbon dioxide. The fuel cell may be a solid oxide fuel cell. The electrolyzer cell may be a molten carbonate electrolysis cell.
