    摘要： An exemplary cooling arrangement for high temperature fuel cell system for substantially reducing the amount of purge gas in a system shutdown situation includes a fuel cell having an anode side, a cathode side, and an electrolyte between the anode side and the cathode side. The cooling arrangement includes a coolant source capable of providing coolant to be used in a cooling process of the high temperature fuel cell system during the system shutdown situation, and a cooling structure in connection with the coolant source arranged in a thermal effect area of the fuel cell stacks. The arrangement also includes the vessel that feeds the coolant into the cooling structure from the coolant source, a heat exchanger that exhausts used coolant from the cooling structure, and an actuating device that uses a triggering force to trigger a coolant flow in the cooling structure, when the system shutdown situation has started.

    摘要： An object of the invention is a recirculated solid oxide electrolyzer cell system, a cell comprising a fuel side (100), an oxygen rich side (102), and an electrolyte element (104) between the fuel side and the oxygen rich side. The system comprises at least one supersonic ejector (120) configured for recirculating (109) a fraction of gas exhausted from the fuel side (100) of each cell and for providing a desired recirculation flow rate of recirculated flow, the ejector having at least one nozzle (122); means (124) for providing at least one primary feedstock fuel fluid to said nozzle of the ejector (120), which nozzle has a convergent-divergent flow channel through which the fluid will expand from an initial higher pressure to a lower pressure; wherein the ejector (120) and possible sources of leakage are contained within structures (144) conveying non-explosive reactant to form leakage and explosive safe structure, and the system comprises a nested arrangement for at least one feed-in route (124) and an exhaust route, the arrangement being nested within the structure (144) conveying non-explosive reactant, and a trim heater (148) arranged within the structures (144) to provide heat to both fuel side (100) and oxygen rich side (102) flows.
