摘要： An electrode structure of a flow battery, a flow battery stack, and a sealing structure of the flow battery stack, wherein the density of the vertical tow in the electrode fiber is larger than the density of the parallel tow. In the electrode fiber per unit volume, the quantity ratio of the vertical tow to the parallel tow is at least 6:4. The electrode structure is composed of an odd number of layers of the electrode fibers, and the porosity of other layers is larger than the porosity of the center layer. The electrode structure is mainly composed of the vertical tows perpendicular to the surface of the electrode, so that, firstly, the contact area between the outer surface of the electrode and the adjacent component can be increased and the contact resistance can be reduced, secondly, the electrode is endowed with good mechanical properties, compared with the original structure, the contact resistance of such structure is reduced by 30%-50%; and the layers of the electrode have different thickness depending on the porosity, after compression, the layers with optimized thickness have a consistent porosity, this compressed uniform structure avoids uneven mass transfer phenomena when the electrolyte flows through the electrode, and reduces the concentration polarization of the battery and thereby improving the battery energy output under the given power.
