| 摘要 |
The present invention relates to a redox flow battery or a fuel battery comprising storing and collecting means for preventing a leakage of a reactant and, more particularly, to a redox flow battery or a fuel battery comprising: at least two end plates; a stack consisting of at least one unit cell interposed between the end plates, the redox flow battery or the fuel battery being characterized by comprising reactant storing and collecting means, provided on the inner side or the outer side of the stack, for preventing a leakage of a reactant. The present invention has an advantage in significantly improving sealing reliability of a redox flow battery or a fuel battery. In addition, even if a leakage of a reactant or a product occurs, the reactant or the product does not leak to the outside, but is stored or collected, and thus, the present invention has an advantage in making maintenance of the redox flow battery or the fuel battery very easy. |
