Tannenberger, H; van den Berghe, P

An electrolyte-electrode assembly for a combustible battery comprising a ceramic solid electrolyte conductive to oxygen ions and impermeable to gas is described. 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 principle 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: 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 of 0 and satisfying the equation a + b = y.
