Abstract
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.
