Abstract
An electrolyte-electrode assembly for a combustible battery comprising a ceramic solid electrolyte conductive to oxygen ions and impermeable to gas. An electrode is secured on one surface of the electrolyte and comprises a porous layer of doped indium oxide composed of dendrites which form trunks having a diameter between 500 and 10,000 A and whose principal axes are penpendicular to the surface of the electrolyte. A continuous layer of ceramic material, conductive to oxygen ions and electrons is interposed between the electrolyte and the electrode and is solid therewith. The electrode can have a second porous layer formed of granules of at least one chromite having the formula: EQU T.sub.1-y Sr.sub.a Ca.sub.b CrO.sub.3 in which T is a rare earth or yttrium or a mixture of these elements and y, a and b are numbers between 0 and 1, being able to take the value 0 and satisfying the equation a + b = y.
