Abstract
A solid oxide fuel cell (SOFC) of improved current collecting efficiency including, an anode, a cathode, an electrolytic layer between the anode and the cathode, and a current collector in an interior space defined by the anode and comprising a current collecting wire layer having a multiple-layered structure including a metal wire and a coating layer on an outer circumferential surface of the metal wire and having a higher melting point than that of the metal wire.
Claims18
A solid oxide fuel cell (SOFC), comprising:
- an anode;
- a cathode;
- an electrolytic layer between the anode and the cathode;
- and
- a current collector in an interior space defined by the anode and comprising a current collecting wire layer having a multiple-layered structure comprising:
- a plurality of metal wires each extending in an axial direction of the SOFC;
- and
- a coating layer on an outer circumferential surface of each of the metal wires, having a higher melting point than that of the metal wires, and comprising a plurality of separate portions intermittently located on the outer circumferential surface of each of the metal wires,
- wherein the current collector comprises:
- a metal tube;
- the current collecting wire layer being on an outer circumferential surface of the metal tube;
- and
- a metal felt layer in a gap between the current collecting wire layer and an inner circumferential surface of the anode.
