Beschreibung
Zusammenfassung:	A perovskite, is used for coating high temperature fuel cell interconnectors (1) and comprises a low lanthanide content lanthanide-alkaline earth metal-transition metal perovskite. A perovskite, for coating interconnectors used in high temperature fuel cells, has the formula ABO3-epsilon, where A = (E1-wLn(omega)-(delta)), B = (G1-zJz), E = alkaline earth metal (preferably Sr or Ca), Ln = a lanthanide (preferably La or Y), G = a transition metal (preferably Mn), J = a transition metal (preferably Co), w = 0.1 to 0.5 exclusive (preferably 0.2), delta = a positive or negative number of value about 0.02, z = 0.01 to 0.5 exclusive (preferably 0.2) and epsilon = a positive or negative number of value about 0.5. Independent claims are also included for the following: (i) a coated interconnector for a high temperature fuel cell, having a coating of the above perovskite applied by HVOF or other thermal spraying at a low powder temperature; and (ii) fuel cell batteries equipped with interconnectors as described above, the interconnector coating having a resistivity of upto 20 m.ohm.cm.
