Title: Thin tubular self-supporting electrode for solid oxide electrolyte electrochemical cells

Abstract

A self-supporting, gas-permeable air electrode tube is made having a sintered structure of calcium-doped LaMnO[sub 3], a density of from 60% to 85% of theoretical density, and a Coefficient of Thermal Expansion of from 10.2 [times] 10[sup [minus]6]/C to 10.8 [times] 10[sup [minus]6]/C, where one end is open and the other end is sealed with a plug. 2 figs.
