Abstract

De nouveaux oxydes de pérovskite à conduction mixte, y compris La0.3Ca0.7Fe07Cr0.3O3-delta, sont utiles comme électrodes dans les applications de cellules de combustible à oxyde solide (SOFC) et de cellules de combustible à oxyde solide réversibles (RSOFC). Lactivité électrochimique dune pérovskite en exemple, sérigraphiée sur un électrolyte de cérium dopé, vers des réactions de réduction en oxygène (ORR) et dévolution en oxygène (OER), a été examinée de 600 à 800 °C dans lair stagnant au moyen dune configuration de RSOFC symétrique. Dans des conditions de circuit ouvert, la pérovskite en exemple a présenté une très faible résistance à la polarisation (R p) de seulement 0,07 O/cm2 à 800 °C, ce qui est comparable à certains des matériaux doxyde aux meilleurs rendements. Une électrode oxydoréductrice faite du matériau en exemple a aussi été déterminée comme très stable et présentant très peu de pertes de rendement et aucun dommage dinterface observé, même après 100 heures à des surpotentiels de 0,4 V (OER) et de - 0,4 V (ORR).
