In one embodiment, the present invention relates to a third electrode for use in a metal-air tricell comprising a support structure coated with a layer of a lanthanum nickel compound and at least one metal mixture, wherein the mixture is adhered to the support structure without the use of an adhesive. In another embodiment, the present invention relates to a metal-air tricell comprising: an air electrode; a metal electrode; and a third electrode, wherein the third electrode comprises a support structure coated with a mixture of a lanthanum nickel compound and at least one metal, wherein the mixture is adhered to the support structure without the use of an adhesive. Additionally, the present invention also relates to a method of forming a third electrode for use in a metal-air tricell comprising the steps of: (A) applying a mixture of a lanthanum nickel compound and at least one metal oxide to a support structure, thereby yielding a coated support structure; and (B) heating the coated support structure in order to reduce the metal oxide present in the lanthanum nickel compound/metal oxide mixture to its corresponding metal and to adhere the mixture to the support structure, thereby yielding a third electrode wherein the third electrode is free of an adhesive.
