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 an inner region (52a) separated respectively from the interface (P1) and the interface (P2).
