Abstract
An interconnect material is formed by combining a lanthanum-doped strontium titanate with an aliovalent transition metal to form a precursor composition and sintering the precursor composition to form the interconnect material. The aliovalent transition metal can be an electron-acceptor dopant, such as manganese, cobalt, nickel or iron, or the aliovalent transition metal can be an electron-donor dopant, such as niobium or tungsten. A solid oxide fuel cell, or a strontium titanate varistor, or a strontium titanate capacitor can include the interconnect material that includes a lanthanum-doped strontium titanate that is further doped with an aliovalent transition metal.
