  • Patent number: 10693152
    Abstract: A fuel cell stack comprises a thin process-gas-connection-endplate with a temperature expansion coefficient which is substantially the same as the temperature expansion coefficient of the plurality of fuel cells and interconnects forming the fuel cell stack, the length and width of the thin process-gas-connection-endplate is matching the length and width of the fuel cells and interconnects and the process-gas-connection-endplate is sealed to the stack of cells and interconnects so the process-gas-connection-endplate, cells and interconnects form one integrated unit, wherein process gas distribution tubes are fixed connected, e.g. welded or brazed to the process-gas-connection-endplate.

  • Patent number: 9865896
    Abstract: A solid oxide fuel or solid oxide electrolysis cell Stack assembly (203) has an improved, simple, cost reducing and robust compression System, housing and Single sided System interface with a flexible-interface-fixture (204) which is rigid enough to fix the at least one cell Stack in the housing when not in Operation, but flexible enough to allow for transfer of the compression force from the flexible compression mat (211) in the top closed end of the housing (201), through the at least one cell Stack and further towards the interface counterpart of the System when in Operation.

  • Patent number: 8841042
    Abstract: A large, scalable SOFC system based on modules, which may be connected in series on the cathode gas side. The fuel cell stacks are aligned side by side and assembled into a stack module with cathode inlets on one face of the module and the cathode outlets on the other face of the module. The stack modules are serially connected in a simple manner by placing the stack modules one after the other, so that the outlet face of the first module faces the inlet face of the second module and so on. In the chamber between two stack modules, the air is cooled for example by addition of cold quench air or by a heat exchanger. This offers compactness, simple stack/system interface and improved system performance. The modules are designed for manufacturability, well-balanced heat management and high fuel utilization.

  • Patent number: 8663863
    Abstract: An interconnect for a fuel cell is made of pressed metal sheet. The interconnect integrates inlets and outlets, flow distributing inlet and outlet-zones seal surfaces and flow paths on both sides of the interconnect all formed and defined by discrete point or oblong protrusions made by the deformation of the sheet. A protrusion on one side of the interconnect corresponds to an indentation on the other side, but since the interconnect consists of three levels, the first side of the interconnect can be designed substantially independently of the second side.
