Abstract
A process for forming a metal supported solid oxide fuel cell, the process comprising the steps of: a) applying a green anode layer including nickel oxide, copper oxide and a rare earth-doped ceria to a metal substrate; b) firing the green anode layer to form a composite including oxides of nickel, copper, and a rare earth-doped ceria; c) providing an electrolyte; and d) providing a cathode. Metal supported solid oxide fuel cells comprising an anode a cathode and an electrolyte, wherein the anode includes nickel, copper and a rare earth-doped ceria, fuel cell stacks and uses of these fuel cells.
Claims5
A metal supported solid oxide fuel cell, comprising:
- (i) a ferritic stainless steel support including a porous region and a non-porous region bounding the porous region;
- (ii) a ferritic stainless steel bi-polar plate located under one surface of the porous region of the support and being sealingly attached to the non-porous region of the support about the porous region thereof;
- (iii) an anode comprising an anode layer located over the other surface of the porous region of the support;
- (iv) an electrolyte comprising an electrolyte layer located over the anode layer;
- and
- (v) a cathode comprising a cathode layer located over the electrolyte layer;
- wherein the anode includes nickel, copper and a rare earth-doped ceria;
- wherein the copper is in a copper oxide selected from copper (II) oxide, copper (I) oxide, a nickel-copper oxide and combinations thereof;
- wherein the anode comprises metal oxides;
- and
- wherein the copper oxide is present in the range around 8 to 12 wt % of the total metal oxide content.
