Title: Support tube for high temperature solid electrolyte electrochemical cell

Abstract

Disclosed is a compound having a fluorite-like structure comprising a solid solution having the general formula [(ZrO.sub.2).sub.1-x (MO.sub.s).sub.x ].sub.1-y [(La.sub.m A.sub.1-m).sub.2-z (Mn.sub.n B.sub.1-n).sub.z O.sub.r ].sub.y where MO.sub.5 is an oxide selected from the group consisting of calcia, yttria, rare earth oxides, and mixtures thereof, x is about 0.1 to 0.3, y is about 0.005 to about 0.06, z is about 0.1 to about 1.9, A is yttrium, rare earth element, alkaline earth element, or mixture thereof, B is iron, nickel, cobalt, or mixture thereof, m is 0.3 to 1, n is 0.5 to 1, and r is 2 to 4. A porous tube made from such a composition can be coated with an electrically conducting mixed oxide electrode such as lanthanum manganite, and can be used in making high temperature electrochemical cells such as solid electrolyte fuel cells.
