1. A method of producing a product stream using a hydrocarbon fuel cell, the method comprising the steps of:
operating the fuel cell to produce electricity, thermal energy, an anode exhaust stream comprising carbon dioxide and water, and a cathode exhaust stream comprising nitrogen gas; and
obtaining a water stream by passing the anode exhaust stream through a phase separator after cooling the anode exhaust stream in one or more cooling heat exchangers; and
using at least a portion of the electricity produced by the fuel cell, powering one or more reactors to chemically change an input stream into a product stream, the input stream comprising at least a portion of the carbon dioxide, at least a portion of the water stream, at least a portion of the nitrogen gas, or combinations thereof;
wherein at least one of the one or more reactors comprises an electrolyzer, the input stream comprises at least a portion of the water stream, and the product stream comprises a hydrogen stream and an oxygen stream.
