Abstract
Disclosed is a structure of a solid oxide fuel cell, including a porous tubular anode support having a plurality of through holes, and an electrolyte layer and a cathode layer sequentially formed on the inner surface of the tubular anode support, so that fuel flows via the plurality of through holes and air flows through the inside of the cathode layer, thus increasing a diffusion rate of fuel and air to thereby increase the reaction rate, resulting in excellent cell performance. This structure eliminates the flow of fuel and air around the outside of the fuel cell, thus preventing the formation of an oxidizing atmosphere at the inside and outside of the tubular cell, thereby increasing lifespan of the cell and ensuring cell reliability.
