Problems solved by technology
[0006] In the existing technology, the sealing performance of the flow battery is not ideal. During use, the problem of electrolyte leakage will occur. The main leakage location is the non-inlet position of the stack, which greatly shortens the life of the flow battery. service life, increasing the maintenance cost of the flow battery

The invention discloses a galvanic pile and a sealing structure of a galvanic pile non-inlet position. The galvanic pile comprises a runner plate, a non-inlet bipolar plate and a non-inlet sealing ring; the runner plate is provided with a forward plate surface and a reverse plate surface; the outer edge of the forward plate surface of the runner plate is provided with a runner groove; the non-inlet bipolar plate is arranged on one side of the forward plate surface of the runner plate; in an assembled state, the non-inlet sealing ring is positioned at the inner side of the runner groove and ispressed between the plate surface of the non-inlet bipolar plate and the forward plate surface of the runner plate. Therefore, electrolyte flowing in the runner groove can not leak out from the contact position of the non-inlet bipolar plate and the runner plate. The galvanic pile also comprises a non-inlet collector plate, and the sizes of the non-inlet collector plate and the non-inlet bipolar plate are smaller than that of the runner plate, so that the galvanic pile is convenient to assemble and transport, and electric shock risks can be avoided.
Description
technical field [0001] The invention relates to the technical field of electric stacks, in particular to an electric stack and a sealing structure at a non-entrance position of the electric stack. Background technique [0002] The development and utilization of renewable energy (such as wind energy and solar energy) has gradually become a research hotspot in the field of new energy technology. [0003] Since energy such as wind energy and solar energy are unstable energy sources, if such energy sources can meet the continuous and uninterrupted electricity demand of users, corresponding energy storage devices must be developed to store such unstable energy sources for backup. [0004] The liquid flow battery in the prior art has gradually become the main device for storing unstable energy such as wind energy and solar energy due to its advantages of good safety, large energy storage, and long life. [0005] The core component of the flow battery is the electric stack. The el...
