CA 2636501
There is provided an SOFC cell and manufacturing method thereof whereby the occurrence of Cr poisoning of the air electrode can be satisfactorily suppressed in an SOFC cell formed by joining together an air electrode with a Cr-containing alloy or the like. A Cr(VI) oxide suppressing state is induced for suppressing the formation of Cr(VI) oxides in an alloy or oxide during a firing process in which an alloy or oxide and an air electrode are fired in a state of being joined together.
La présente invention concerne une cellule pour pile à combustible à oxyde solide comportant, joints ensemble, un alliage ou un oxyde contenant du Cr et une électrode à air, dans laquelle le risque d~empoisonnement au Cr de l~électrode à air pouvant être inhibé efficacement ; et son procédé de production. Dans l~opération de cuisson au cours de laquelle l~alliage ou l~oxyde et l~électrode à air joints l~un à l~autre sont cuits, l~on induit une condition d~inhibition de l~oxyde de Cr(VI) pour inhiber la formation d~oxyde de Cr(VI) dans l~alliage ou l~oxyde.
