Abstract
The invention comprises a solid oxide fuel cell system comprising at least two solid oxide fuel cell stacks and at least one extension member. Each solid oxide fuel cell stack includes a plurality of solid oxide fuel cells. Each cell is separated by an interconnect. The extension member joins at least one interconnect of one of the solid oxide fuel cell stacks with a corresponding interconnect of another of the solid oxide fuel cell stacks. The invention further includes a method of fabrication.
Claims18
A solid oxide fuel cell system comprising:
- at least two solid oxide fuel cell stacks, each stack including a plurality of solid oxide fuel cells, wherein each adjoining solid oxide fuel cell separated by an interconnect;
- and
- at least one extension member joining at least one interconnect of one of the at least two solid oxide fuel cell stacks with a corresponding at least one interconnect of another of the at least two solid oxide fuel cell stacks, such that at least one of the plurality of solid oxide fuel cells in one of the at least two solid oxide fuel cell stacks is connected in parallel electrically with at least one of the plurality of solid oxide fuel cells of another of the at least two solid oxide fuel cell stacks.
A method of fabricating a solid oxide fuel cell system comprising the steps of:
- providing at least two solid oxide fuel cells stacks, the stacks including a plurality of solid oxide fuel cells each separated by an interconnect;
- and
- associating at least one interconnect of one of the at least two solid oxide fuel cell stacks to a corresponding interconnect of at least one of the remaining at least two solid oxide fuel cell stacks by way of an extension member.
A solid oxide fuel cell system comprising:
- at least three solid oxide fuel cell stacks, each stack including a plurality of solid oxide fuel cells, wherein each adjoining solid oxide fuel cell is separated by an interconnect;
- and
- at least one extension member connecting at least one interconnect of one of the at least three solid oxide fuel cell stacks with a corresponding interconnect of each of the remaining fuel cell stacks.
