Abstract
The solid oxide fuel cell according to the present invention is directed to a support type or self-support type single cell in which four sides or opposite two sides of corners of the single cell are downwardly bent in an inverted U shape and have gas channels in the inner side and/or outer side with a straight line structure or lattice shape structure, so that a separating plate can be used without gas channels or channel support. A smooth flow of a reaction gas is implemented in the directions of the air electrode and the fuel electrode of a single cell.
Claims9
A solid oxide fuel cell defined as a single cell having a fuel electrode, an electrolyte, and an air electrode, wherein four sides or opposite two sides of corners of the single cell are downwardly bent in an inverted U shape, and gas channels are integrally formed in at least one of said fuel electrode, electrolyte and air electrode defining an inner side and/or an outer side of the single cell.
