The SOFC system (1) comprising: - a fuel reformer (102) for reforming a gaseous hydrocarbon stream (100) and steam (404) into a hydrogen rich gas (103), - a solid oxide fuel cell stack (2) including an anode (4) and a cathode (3) for electrochemically reacting the hydrogen rich gas (103) and a cathode air stream (204) to produce electricity, an anode exhaust stream (104) and a cathode depleted air stream (205), wherein the anode exhaust stream (104) and the cathode depleted air stream (205) are kept separate, - a burner (105) for combusting a mixture of the anode exhaust stream (104) and a fresh air stream (300) to complete combustion and produce heat for the reformer (102), - a control unit (601) and a blower (302), the control unit (601) controlling the blower (302) for controlling the mass flow rate of the fresh air stream (300) to provide heat to the reformer (102) to reform the gaseous hydrocarbon stream (100) and to produce a burner exhaust stream (106), - and a heat exchanger (107), wherein condensed water (403) from the anode exhaust stream (104) or the burner exhaust stream (106) is heated to generate steam (404). |
