  • Publication number: 20250087713
    Abstract: A carrier structure for electrodes of a fuel cell. The structure has a duct wall and a tubular ducting volume. The duct wall forms the tubular ducting volume and includes an outer surface facing a surrounding and an inner surface facing the tubular ducting volume. The tubular ducting volume conducts a first supply flow comprising an oxidant. The duct wall provides a second supply flow within the duct wall, the second supply flow being a reductant. The duct wall separates the first supply flow in the tubular ducting volume from the second supply flow within the duct wall and the surrounding of the carrier structure. A primary power coating layer is applied on the inner surface of the duct wall, arranged between the first supply flow and the second supply flow. The coating layer generates electrical energy from the first supply flow and the second supply flow.

  • Publication number: 20240154144
    Abstract: A solid oxide fuel cell stack for an aircraft engine includes ring-shaped fuel cell assemblies of parallel tubular oxide fuel cells circumferentially around a central axis. A first stacking manifold for each fuel cell assembly is in contact with a first side of the individual fuel cell assembly, a second stacking manifold is in contact with a second side of the individual fuel cell assembly, and a central recess for leading an engine shaft through. Each fuel cell includes a tubular anode and tubular cathode, the fuel cell assemblies stacked in an axial direction through pairs of first and second stacking manifolds contacting each other. Each first stacking manifold includes a hydrogen inlet and is connected to first ends of the anodes of the fuel cells. Each second stacking manifold includes a hydrogen and steam outlet and is connected to second ends of the anodes of the fuel cells.

  • Publication number: 20230246204
    Abstract: An interconnecting device for compact solid oxide fuel cells includes a body having first and second interface surfaces on distinct body sides. The first interface surface includes spaced apart anode and cathode exhaust inputs. The second interface surface includes spaced apart fuel and air supply ports. The anode exhaust input fluidly communicates with the fuel supply port and/or anode exhaust outlet arranged at a distance to the first and second interface surfaces. The cathode exhaust input fluidly communicates with the air supply port and/or cathode exhaust outlet arranged at a distance to the first and second interface surfaces. The first electrical port is arranged at or in the cathode exhaust input and is connectable from the first interface surface. The second electrical port is arranged at or in the fuel supply port and is connectable from the second interface surface, and is electrically connected to the second electrical port.

  • Patent number: 10411277
    Abstract: A gas circuit for a solid oxide fuel cell system may comprise an anode gas segment in which an anode gas exiting from a gas space of an anode of a solid oxide fuel cell flows, a recirculation segment for recirculating at least a part of the anode gas back to a combustion gas processing appliance arranged in the gas circuit and in which fuel is processed to combustion gas for the solid oxide fuel cell, wherein a conveying appliance for recirculating the anode gas, and a division appliance that divides the anode gas into a recirculation stream and a residual gas stream to be discharged from the gas circuit, are arranged in the gas circuit, wherein the conveying appliance is arranged upstream of the division appliance in the anode gas segment. The present disclosure further relates to a solid oxide fuel cell system having a gas circuit.

  • Publication number: 20140342256
    Abstract: A method for producing an adjustable gas composition to be used as an anode gas for a fuel cell, such as a solid oxide fuel cell (SOFC), is performed in a system comprising (a) a fuel processing unit (1), wherein a hydrocarbon fuel raw material is converted to reformate gas, a combustion unit (2), wherein the reformate gas from the fuel processing unit (a) is partially or completely burned with an oxygen gas source, and (c) a post-processing unit (3), wherein the equilibrium composition of the reformate gas is catalytically changed by varying the temperature of the catalytic bed in the unit or by partially combusting the feed gas to the post-processing unit in the preceding combustion unit (2).
