1. An apparatus for manufacturing a unit cell, in which one of a positive electrode and a negative electrode is stacked on a top surface of a first separator that is continuously supplied, and an other of the positive electrode and the negative electrode is stacked on a bottom surface of the first separator to bond the positive electrode and the negative electrode to the first separator, the apparatus comprising:
a reservoir in which at least two transfer rollers that rotate while the first separator passes therethrough are mounted, and a solvent is stored at a predetermined level; and
a chamber into which the first separator passing through the reservoir is put together with the positive electrode and the negative electrode, each electrode cut by a predetermined size, and guide rollers are disposed so that the negative electrode and the positive electrode move to the top surface and the bottom surface of the separator, respectively,
wherein, while the first separator passes through the reservoir, at least a partial region of the first separator is dipped in the solvent within the reservoir.
