    • The invention concerns a method of operating a fuel cell system (1) in fuel cell mode, the fuel cell system (1) comprising at least one fuel cell (2) comprising an anode (2a), a cathode (2b) and an electrolyte (2c) provided between the anode (2a) and the cathode (2b), the fuel cell (2) being arranged for an internal reformation of hydrocarbon compounds inside the anode (2a), an anode exhaust conduit (4) connecting the anode outlet (2d) and a fuel conduit (6) and comprising a methanation unit (3a), a water-gas shift reactor (3b), and a water vapor condenser or water removal unit (12), the anode exhaust conduit (4) or the fuel conduit (6) comprising a carbon dioxide separation unit (11), and the fuel conduit (6) connecting a fuel cell system inlet (7) and an anode inlet (2e), the method comprising the steps of a) feeding feed gas into the fuel conduit (6) via the fuel cell system inlet (7), the feed gas comprising hydrocarbon compounds, b) controlling the methanation unit (3a) to produce methane and controlling the water gas shift reactor (3b) to produce hydrogen so that in a feed gas mixture supplied to the anode inlet (2e) a molar ratio of hydrogen to carbon at a selected operation temperature of the fuel cell (2) prevents the formation of solid carbon, wherein the molar ratio of oxygen to carbon in the feed gas mixture supplied to the anode inlet is smaller than 1, preferably smaller than 0.1, c) wherein carbon dioxide is separated from an anode exhaust or the feed gas mixture in the carbon dioxide separation unit (11), wherein water is not added to the feed gas or the feed gas mixture supplied to the anode inlet (2e), and wherein water vapor contained in the anode exhaust is separated in a water vapor condenser or water removal unit (12).
