Title:
COLLECTOR PLATE
Document Type and Number:
Japanese Patent JP2019012694
Kind Code:
A
Abstract:
To provide a collector plate provided in a redox flow battery having a low cell resistivity.SOLUTION: In a collector plate of a redox flow battery including an ion exchange membrane, a collector plate, and an electrode disposed between the ion exchange membrane and the collector plate, a plurality of flow path networks through which an electrolyte flows are formed on the electrode side surface. Each of the plurality of flow path networks has a rectangular shape, the length of the short side is 5 mm or more and 70 mm or less, and the effective area ratio is 60% or more. Here, the effective area ratio is (the sum of the effective electrode areas of the plurality of flow path networks)/{(the sum of the areas of the plurality of flow path networks)+(the sum of the areas of portions between the plurality of flow path networks)}.SELECTED DRAWING: Figure 2
