Problems solved by technology

[0012] This reduces the current collection efficiency of the fuel cell
In addition, since the reaction occurs more intensively at the inflow inlet, the inflow inlet is more significantly degraded than the outflow outlet
[0013] Therefore, although the outflow port deteriorates relatively lightly, significant deterioration in the inflow port greatly reduces the service life of the fuel cell

Abstract

The invention relates to a solid oxide fuel cell with longitudinal channels and transverse channels formed on an electronic separator. A solid oxide fuel cell according to a preferred embodiment of the present invention includes: a battery cell formed by laminating an anode, an electrolyte, and a cathode; A longitudinal channel parallel to the gas flow direction and a transverse channel crossing the reactant gas flow direction are formed; and a collector interposed between the battery unit and the separator. The width of the longitudinal channel increases from the reaction gas inflow opening towards the reaction gas outflow opening.

Description

technical field [0001] The present invention relates to a solid oxide fuel cell having longitudinal channels and transverse channels, and more particularly, to a solid oxide fuel cell having a Longitudinal and transverse channels. Background technique [0002] This application claims priority to Patent Application No. 10-2012-0148194 filed with the Korean Intellectual Property Office on December 18, 2012, the entire contents of which are incorporated herein by reference. [0003] A fuel cell is an energy conversion device utilizing an electrochemical reaction of a fuel with an oxidant, which converts chemical energy of the fuel into electrical energy without converting the chemical energy into thermomechanical energy. Therefore, the power generation efficiency of the fuel cell is higher than that of the conventional power generation system, and the fuel cell is environmentally friendly and is being actively researched as a future energy source. [0004] Fuel cells can be c...
