SOLID-OXIDE FUEL CELL

摘要

This solid-oxide fuel cell (10) is provided with a solid-electrolyte layer (30), a barrier layer (40), and an air electrode (50). Said air electrode (50) has an air-electrode collection layer (51) and an air-electrode active layer (52). Said air-electrode active layer (52) contains a plurality of narrow voids (SL) in an interfacial region (52a) within a prescribed distance (Da) from the interface (P2) between the air-electrode collection layer (51) and the air-electrode active layer (52).
