PURPOSE: A fuel cell is provided to reduce voltage drop by the resistance of a current collector while uniformizing the distribution of unit cell voltages. CONSTITUTION: A fuel cell comprises: a plurality of tube type unit cells(100) which comprises a first electrode layer, an electrolyte layer, and a second electrode layer radially arranged from the center axis of the fuel cell; an internal current collector which are arranged inside of the each unit cell; and external current collectors(210,220) each of which is formed on the each outer circumference of the unit cells and has a plurality of connection parts(221) for electrically connecting the unit cells to each other. The connection part forms two or more electric path. The connection parts are spaced apart at constant intervals. |
