Abstract
A fuel cell includes a unit cell, a cell fixing member and a welding portion. The unit cell includes a first electrode layer, an electrolyte layer surrounding the first electrode layer, a second electrode layer surrounding the electrolyte layer while exposing an end portion of the electrolyte layer, and a coating layer formed by coating a mixture of ceramic and metal on the exposed end portion of the electrolyte layer. The cell fixing member includes a flow tube inserted into the unit cell, a fixing tube provided to an outside of the flow tube, and a connecting portion connecting the fixing tube and the flow tube to each other and to restrict an insertion depth of the electrolyte layer and the first electrode layer. The welding portion fixes and seals the coating layer and the inner circumferential surface of the fixing tube to each other.
