The present embodiment describes a method of forming different layers in a solid oxide fuel cell. The method begins by preparing slurries which are then delivered to a spray nozzle. The slurries are then atomized and sprayed subsequently onto a support to produce a layer which is then dried. In this embodiment different layers can comprise an anode, an electrolyte and a cathode. Also the support can be a metal or a metal oxide which is later removed.

Formation of solid oxide fuel cells by spraying

A solid oxide fuel cell comprising a cathode, an electrolyte, a functional layer and an anode support. The anode support comprises A-B-C: A is a nitrate, an oxide, a salt or a carbonate selected from the group of: alkali, alkaline oxide, alkaline earth metal or combinations thereof, B is selected from the group of: Fe, Ni, Cu, Co or combinations thereof, and C is selected from the group of: PSZ, YSZ, SSZ, SDC, Ce doped SSZ, GDC or combinations thereof. In the solid oxide fuel cell A ranges from about 0 to about 20 wt % of the anode support, B ranges from about 0.1 to about 70 wt % of the anode support and C ranges from about 0.1 to about 60 wt % of the anode support.

Modified solid oxide fuel cell

A solid oxide fuel cell comprising an electrolyte, an anode and a cathode. In this fuel cell at least one electrode has been modified with a promoter using gas phase infiltration.
