1. A method for manufacturing a solid oxide fuel cell stack, the method comprising the steps of:

  • manufacturing a unit cell module comprising at least one unit cell formed on the outer surfaces of a flat tubular porous support and having a first gas channel inside of the tubular support and a second gas channel outside of the tubular support, a first electrical interconnector coated on the front end of the support and at least a portion of the outer surfaces so as to be connected to a first electrode of the unit cell, and a second electrical interconnector coated on the rear end of the support and at least a portion of the outer surfaces so as to be connected to a second electrode of the unit cell; and

    stacking the unit cell modules such that the electrical interconnectors come into contact with each other;

    wherein first gas channels are formed in the flat tubular support, second gas channels and unit cells are formed at the central portions of the outer surfaces of the flat tubular support, and the electrical interconnectors are formed on both side edges of the outer surfaces of the flat tubular support; and

    wherein the central portions of the outer surfaces of the support are grooved to a predetermined depth, and the grooved supports are stacked to form second gas channels.
