1. The Proton membrane exchange we produce has certain advantages in production costs, thereby reducing the overall cost of proton exchange membranes. 2. The Proton membrane exchange we produce shows better performance than traditional Nafion membranes, demonstrating its potential in large-scale energy storage applications. 3. The Proton membrane exchange we produce can effectively block vanadium ions through the Donnan exclusion effect, thereby enhancing the membrane's vanadium barrier capability.
