Abstract
A method for preparing an electrode for a solid oxide fuel cell, in which a conductive material, such as a metal, is electrodeposited onto a porous electrode comprising a conductive material and an electrolyte. The method allows metals to be added directly to a porous electrode without the need for subsequent reduction steps. The method also permits the conductive materials to be deposited in controlled, layered structures, thereby enabling the use of different metals to achieve desired properties.
Claims22
A method of making an electrode for use in a solid oxide fuel cell, said method comprising:
- providing a porous electrode material comprising a first conductive material and an electrolyte;
- and
- electrodepositing on the porous electrode material a second conductive material, wherein the second conductive material is disposed at least partially within the pores of the porous electrode material.
A method of making a solid oxide fuel cell comprising:
- providing a cathode;
- providing an anode;
- providing an electrolyte;
- disposing the electrolyte at least partially between the anode and cathode;
- wherein at least one of providing a cathode and providing an anode comprises:
- forming a porous electrode containing a first conductive material and a dense electrolyte composite;
- and
- electrodepositing on the porous electrode material a second conductive material, wherein the second conductive material is disposed at least partially within the pores of the porous electrode material.
