SOLID-OXIDE FUEL CELL

摘要

A solid oxide fuel cell (10) comprises a solid electrolyte layer (30), a barrier layer (40), and a cathode (50). The cathode (50) includes a cathode current collecting layer (51) and a cathode active layer (52). The cathode active layer (52) includes a plurality of micro-cracks (SL) in a surface region (52a) within a predetermined distance (Da) from the interface (P2) between the barrier layer (40) and the cathode active layer (52).
