Abstract
Multiple gas inlet or outlets for a SOC unit is provided by stacked layers with cut outs for gas channels which overlap.
Claims21
Solid oxide electrolysis cell stack comprising a plurality of stacked cell units, each unit comprises a cell layer and an interconnect layer, wherein one interconnect layer separates one cell unit from the adjacent cell unit in the cell stack, wherein at least one of said layers in at least one cell unit has at least one primary gas inlet opening and wherein at least one adjacent layer in the same cell unit has at least one secondary gas inlet opening, wherein said primary gas inlet opening and said secondary gas inlet opening partly overlap, the overlap defines a common gas inlet zone where inlet gas flows from the primary gas inlet opening to the secondary gas inlet opening.
Method for channelling inlet gas to a cell unit in a solid oxide electrolysis cell stack comprising a plurality of stacked cell units, each unit comprises a cell layer and an interconnect layer, wherein one interconnect layer separates one cell unit from the adjacent cell unit in the cell stack, wherein at least one of said layers in at least one cell unit has at least one primary gas inlet opening and at least one adjacent layer in the same cell unit has at least one secondary gas inlet opening, wherein said primary gas inlet opening and said secondary gas inlet opening partly overlap, the overlap defines a common gas inlet zone, the method comprising the steps of,
- providing an inlet gas to the at least one primary gas inlet opening
- flowing the inlet gas in a first direction through said primary gas inlet opening
- flowing the inlet gas in a second direction through a common gas inlet zone
- flowing the inlet gas in a third direction through the at least one secondary inlet gas opening
