In some examples, a solid oxide fuel cell system including a solid oxide fuel cell; an ejector, wherein the ejector is configured to receive a fuel recycle stream from a fuel side outlet of the solid oxide fuel cell and also receive a primary fuel stream, wherein the ejector is configured such that the flow of the primary fuel stream draws the fuel recycle stream into the ejector and mix the fuel recycle and primary fuel stream to form a mixed fuel stream including methane and higher hydrocarbons; and a higher hydrocarbon reduction unit configured to receive the mixed fuel stream from the ejector and remove a portion of the higher hydrocarbons via a catalytic conversion process to form a reduced higher hydrocarbon fuel stream, wherein a fuel side inlet of the solid oxide fuel cell is configured to receive the reduced higher hydrocarbon fuel stream from a reduction unit.
