Apparatus for Inspecting Unit Cell

An apparatus for inspecting a unit cell, the apparatus comprising:

• a transfer part configured to transfer a plurality of unit cells in a transfer direction, wherein the transfer part comprises a plurality of transfer rollers arranged along the transfer direction, wherein each of the plurality of unit cells has an electrode;
• and
• an optical inspection part configured to optically sense the unit cells when each of the unit cells is disposed at an inspection position along the transfer direction,
• wherein each of the plurality of unit cells comprises an electrode tab extending from the respective electrode to an exterior region near a respective separator provided in each of the plurality of unit cells,
• wherein the optical inspection part is provided to set a region of interest, wherein the region of interest comprises at least a portion of the respective electrode tab disposed at the inspection position, and
• wherein an adjacent transfer roller of the plurality of transfer rollers is disposed adjacent to the region of interest, so as to not overlap the region of interest.
