ABSTRACT:
The present invention relates to a solid oxide fuel cell in which an anode is formed with a hollow portion, and the hollow portion may be used as a gas diffusion path, thereby improving gas diffusion performance, and the hollow portion may be also used as a reinforcement hole for reinforcing a strength or a current collecting hole for increasing a current collecting efficiency, thereby improving a cell strength and also increasing an efficiency of producing electric energy. The solid oxide fuel cell has an electrolyte layer; an anode; a cathode; and a hollow portion formed in the anode.
