Abstract
It is an object to shorten current path between an anode and a cathode in a tube type SOFC and thereby to decrease resistance. The tube type fuel cell contains a tube type electrolyte placed between an anode and a cathode, wherein an auxiliary electrode is provided over the entire region of a cell reaction region on at least one of the anode and cathode. The current path is shortened and resistance is decreased, because the anode auxiliary electrode or cathode auxiliary electrode is provided over the entire peripheral surface of the anode or cathode, and the current path in the auxiliary electrode has a greatly increased cross-sectional area.
