A method for manufacturing a fuel cell assembly, comprising:
- providing at least one fuel cell unit, wherein providing said at least one fuel cell unit comprises
- providing at least one substrate;
- and
- disposing at least one fuel cell component layer on said at least one substrate, said at least one component layer comprising at least one of an interconnect, an anode, a cathode, and an electrolyte;
- wherein disposing comprises depositing said at least one component layer using an expanding-thermal-plasma coating apparatus.
A method for manufacturing a fuel cell assembly, comprising:
- providing at least one fuel cell unit, wherein providing said at least one fuel cell unit comprises
- providing at least one substrate;
- and
- disposing a plurality of fuel cell component layers on said at least one substrate, said plurality of component layers comprising
- an anode comprising from about 20 volume percent to about 80 volume of at least one of stabilized zirconium oxide and cerium oxide and the balance comprising at least one of nickel and nickel oxide,
- a cathode comprising from about 20 volume percent to about 80 volume percent of at least one of stabilized zirconium oxide and cerium oxide and the balance comprising lanthanum strontium manganite, and
- an electrolyte comprising at least one of stabilized zirconium oxide and cerium oxide;
- wherein disposing comprises depositing said at least one component layer using an expanding-thermal-plasma coating apparatus.
A fuel cell assembly manufactured by a method, the method comprising
- providing at least one fuel cell unit, wherein providing said at least one fuel cell unit comprises
- providing at least one substrate;
- and
- disposing at least one fuel cell component layer on said at least one substrate, said at least one component layer comprising at least one of an interconnect, an anode, a cathode, and an electrolyte;
- wherein disposing comprises depositing said at least one component layer using an expanding-thermal-plasma coating apparatus, wherein said at elast one layer comprises at least one gradient in at least one parameter selected from the group consisting at least one gradient in at least one parameter selected from the group consisting of composition and porosity, and wherein said at least one gradient of said at least one layer exists in a direction substantially parallel to said substrate.
A fuel cell assembly manufactured by a method, the method comprising:
- providing at least one fuel cell unit, wherein providing said at least one fuel cell unit comprises
- providing at least one substrate;
- and
- disposing a plurality of fuel cell component layers on said at least one substrate, wherein each layer comprising said plurality of layers has a thickness in the range from about 1 micron to about 50 microns, and wherein said plurality of component layers comprises
- an anode comprising from about 20 volume percent to about 80 volume percent of at least one of stabilized zirconium oxide and cerium oxide and the balance comprising at least one of nickel and nickel oxide,
- a cathode comprising from about 20 volume percent to about 80 volume percent of at least one of stabilized zirconium oxide and cerium oxide and the balance comprising lanthanum strontium manganite, and
- an electrolyte comprising at least one of stabilized zirconium oxide and cerium oxide;
- wherein disposing comprises depositing said at least one component layer using an expanding-thermal-plasma coating apparatus, wherein said at least one layer comprises at least one gradient in at least one parameter selected from the group consisting of composition and porosity, and wherein said at least one gradient of said at least one layer exists in a direction substantially parallel to said substrate.
