Abstract

Det er frembrakt et rimelig, lanthanidsubstituert, dimensjons- og varmestabilt, gasspermeabelt, elektrisk ledende, porøst, keramisk luftelektrodemateriale av lanthanid-substituert, ympet lanthanmanganitt, som anvendes som katode i høytemperaturbrenselceller og -generatorer med elektrolytt av fast oksid. Luftelektrodematerialet ifølge oppfinnelsen har en mye lavere fremstillingskostnad som resultat av anvendelse av en rimeligere lanthanidblandlrig, enten en naturlig blanding eller et uferdig lanthanid- konsentrat oppnådd fra en naturlig blanding som er under- kastet ufullstendig rensing, som råmateriale istedenfor en del av eller alt det kostbarere, individuelle lanthan. Det blandete lanthanid inneholder primært en blanding av i det minste La, Ce, Pr og Nd eller i det minste La, Ce, Pr, Nd og Sm i dets lanthanidinnhold, men kan også inneholde mindre mengder andre lanthanider og sporurenheter. An- vendelsen av lanthanider istedenfor noe av eller alt lanthan øker også luftelektrodens dimensjonsstabilitet. Denne rimelige luftelektrode kan fremstilles som en katode for anvendelse i høytemperaturbrenselceller og -generatorer med fast oksid.
