Product Title
VRFB Test Stack with 25 cm² Active Area | Rated Current Density 300 mA/cm² for Lab Research & Industrial Testing
Product Overview
This vanadium redox flow battery (VRFB/VFB) test stack is specially developed for laboratory research in universities, research institutes, and performance inspection of upstream and downstream products from vanadium battery manufacturers. Equipped with a standardized 25 cm² electrode active area and standard electrolyte flow parameters, it accurately simulates the operating conditions of industrial-scale vanadium energy storage stacks.
It serves as core test equipment to verify the performance of ion exchange membranes, vanadium electrolytes, electrode substrates and other key raw materials, support formula optimization and pre-production inspection. The test data features outstanding stability and repeatability, which perfectly meets the requirements of lab-scale R&D of vanadium flow batteries.
Core Technical Specifications
Electrode Active Area: 25 cm²
Electrolyte Specific Flow Rate: 10 mL/cm²
Rated Current Density: 180~400 mA/cm²
Standard Operating Energy Efficiency: 80%
Key Product Advantages
Adopted fixed 25 cm² standard active area to control experimental variables strictly, enabling comparable data across contrast experiments and academic papers.
Pre-set standard electrolyte specific flow rate at 10 mL/cm² to eliminate repeated fluid parameter debugging; charge-discharge cycling tests can be launched immediately after setup.
The rated current density of 180~400 mA/cm² matches the actual working range of mass-produced industrial stacks, so test data can directly guide production process improvement.
The well-tested sealing structure effectively prevents liquid leakage and guarantees stable performance during long-term continuous cycling experiments.
Modular detachable design allows quick replacement of ion exchange membranes, electrodes, gaskets and other consumables, greatly shortening disassembly and assembly time between experiments.
Steady energy efficiency up to 80% thanks to mature assembly technology, which can intuitively reflect the barrier property of membranes and electrochemical activity of electrolytes.
