- Components included in the unit cell 10 will be described as a lower cathode 11, a lower first separator 12, and a lower anode 13. In addition, however, it is not limited thereto, and configurations included in each unit cell are not different from each other.
- the second separator 30 has been described as a configuration not included in a unit cell, but this is only for convenience of explanation, and the separator/cathode/separator/anode structure may be defined as a unit cell, and is not particularly limited. .
