Abstract
The present invention generally relates to ceramic anodes for use in solid oxide fuel cells, whereby the anodes are comprised primarily of ceramic material.
Claims21
A porous anode, comprising:
- a porous first ceramic material;
- and
- an electronically conductive material disposed along the inner walls of at least one pore of the porous first ceramic material,
- the electronically conductive material comprising a second ceramic material;
- the anode being produced by
- adding a salt of the second ceramic material to the porous first ceramic material;
- heating the resulting structure so as to give rise to the porous anode comprising the electronically conductive material being disposed along the inner walls of the pores of the porous ceramic first material, and
- there being substantially no metal added to the anode.
