A unit cell of a solid oxide fuel cell (“SOFC”) and a fuel cell stack including the SOFC are disclosed. The SOFC may include a first electrode formed in a hollow cylinder shape, a second electrode formed on an outer surface of the first electrode, an electrolyte layer formed between the first electrode and the second electrode and a cap coupled to an end portion of the first electrode. A seating groove may be formed in the cap such that a conductor may be inserted into the seating groove and be in surface contact with the cap. The cap may include a conductive material and a current collection area of the unit cell may be broad when the fuel cell is included in, a fuel cell stack.
