AI Technical Summary
Existing vanadium redox flow battery stacks suffer from insufficient compatibility, leading to performance degradation, high leakage risk, and limited energy efficiency and economy. In particular, bipolar plate corrosion and carbon felt adsorption of vanadium ions result in short service life and safety hazards.
The proton exchange membrane, which is resistant to strong acids and vanadium ion swelling, is made into a tubular structure. Combined with a fully sealed design, carbon felt and bipolar plates are eliminated. Vanadium corrosion-resistant conductive electrodes are used to ensure electrolyte flow matching and multiple seals, reduce mass transfer resistance, and improve the stability and safety of the fuel cell stack.
It significantly improves the operational stability and energy conversion efficiency of the fuel cell stack, reduces the risk of electrolyte leakage, simplifies the maintenance process, reduces the total life cycle cost, and meets the requirements of green energy storage.
