Abstract
A solid oxide fuel cell is disclosed. The solid oxide fuel cell comprises an electrolyte disposed between and in ionic communication with a first electrode and a second electrode to form an electrochemical cell. At least one spacer is disposed in contact with the electrochemical cell. A mat is disposed adjacent to the spacer. A method for making a solid oxide fuel cell is also disclosed.
Claims46
A solid oxide fuel cell, comprising:
- an electrolyte disposed between and in ionic communication with a first electrode and a second electrode, forming an electrochemical cell;
- a mat disposed adjacent to and in physical contact with at least a portion of said electrochemical cell;
- and
- a spacer disposed around said mat.
A solid oxide fuel cell stack, comprising:
- at least two solid oxide fuel cells, wherein each solid oxide fuel cell comprises an electrolyte disposed between and in ionic communication with a first electrode and a second electrode, forming an electrochemical cell, a mat disposed adjacent to and in physical contact with at least a portion of said electrochemical cell, and at least one spacer disposed around said mat;
- and
- an interconnect disposed in between adjacent fuel cells and in electrical communication with said mat.
A method for manufacturing a solid oxide fuel cell stack, comprising:
- disposing an electrolyte between and in ionic communication with a first electrode and a second electrode to form an electrochemical cell;
- disposing a mat and in physical contact with at least a portion of said electrochemical cell;
- disposing at least one spacer around said mat;
- and
- disposing an interconnect in electrical communication with said mat on a side opposite said electrochemical cell.
A solid oxide fuel cell stack comprising:
- at least two solid oxide fuel cells, wherein each solid oxide fuel cell comprises an electrolyte disposed between and in ionic communication with a first electrode and a second electrode, forming an electrochemical cell;
- and
- an interconnect disposed between adjacent fuel cells, wherein said interconnect has at least one flow section disposed between an expander and a periphery, said expander is disposed around said interconnect up to about 360°.
