Release time:2024.11.13 Number of views:85

The patent abstract shows that the present invention relates to an integrated electrode frame and stack for a vanadium flow battery, comprising: a main frame body, a hollow center of the main frame body, and electrolyte flow channels on the lower and upper parts of both sides of the main frame body; The front of the main frame is equipped with an ion membrane installation groove, and the back is equipped with a first electrode groove; The first cover plate is hollow in the middle and has a second electrode groove on the surface facing the front of the main frame. The inner edges of the first and second electrode grooves are both equipped with toothed channel grooves that are connected to the inlet channel. The outer edge of the second electrode groove is equipped with a protruding pressure film part embedded in the ion film installation groove; The second cover plate has at least a hollow center; The first cover plate and the second cover plate are respectively fitted into the cover plate installation slots on both sides of the main frame and cover at least all electrolyte flow channel areas. This technical solution not only effectively connects traditional scattered components into an integrated structure, but also reduces the possible pathways of electrolyte leakage and improves the sealing performance of the fuel cell stack.
