摘要： The present invention relates to a solid oxide electrolyser cell system (10) comprising an electrolysis stack (12) comprising an anode, a cathode and a solid-oxide electrolyte. The anode comprises an anode inlet (14). The system (10) further comprises a sweep gas supply (16) for supplying a sweep gas to the anode via the anode inlet (14), and a sweep gas supply flow path (18) defining a flow path between the sweep gas supply (16) and the anode inlet (14). The system (10) further comprises a first heat exchanger (30) in fluid communication with the sweep gas supply flow path (18). The first heat exchanger (30) is also in fluid communication with a fluid stream (26) having a source external to the solid oxide electrolyser cell system (10) and defining an external stream flow path (28). The first heat exchanger (30) is configured to exchange heat between the sweep gas supply flow path (18) and the external stream flow path (28). The present invention also relates to a method of operating such a solid oxide electrolyser cell system (10) by exchanging heat between the external stream flow path (28) and the sweep gas supply flow path (18) through the first heat exchanger (30).
