Features:

· Single cell voltage range: 1.2V ~ 1.6V (depending on Vanadium electrolyte composition) 

· Cell current density: 40 ~ 100 mA / cm^2 ( maximum 4.9A of possible current draw for a 7cm x 7cm reactive area)   

· Manifold Blocks are made of anti-corrosive PTFE materials to withstand acids

· Large reactive area provides uniform and reliable test data

· Cathode materials are changable according to the test conditions

· Easy assembly and disassembly

Reactive Area - Multiple Configurations 

· Standard cell comes with 3 interchangeable frames and gaskets for testing multiple parameters (please click the bottom left picture below for details): 

o 7x7cm

o 5x5cm

o 3x3 cm

· Custom reactive area sizes up to 20cm x 30cm can be requested at an extra cost

Compression Pressure

· 87 PSI (0.6Mpa), ~300KG Force is recommended

· 116 PSI (0.8Mpa) Max.

Unit Cell Internal Structure (all components are included)

All components, Manifold Blocks, Current Plates, Bipolar Plates, Gaskets, Frames, Carbon Felts, Membranes, O-Rings, liquid inlet and outlet ports, are included for immediate use. Please click here to order extra Internal Components if it is needed.

Bipolar Plates

· High electrical conductivity, chemical resistance, and high mechanical strength for toughness

· These highly flexible plates offer performance comparable to conventional graphite plates BUT have excellent resistance to breakage and have less defects

· Only ~0.7mm in thickness, this keeps cells thinner when stacked compared to graphite plates ( porous and brittle in nature; needs to be thick structurally)

· Needs frequent replacement, please order from the "Related Products" category below

External Dimensions

  ·  126mm (L) x 126mm (W) x 67mm (H)

Procedure for Testing Flow Cell -- click the picture to enlarge:

· A jig or pressing machine is required to tightly press the cell together in order to suppress leakage of electrolyte solutions during live tests. Please order a hydraulic jig separately from below or use your own jig -- WARNING: Never exceed a max. pressure of 0.8MPa to avoid damage to the flow cell

· Peristaltic pump and battery analyzer are also available for making a low-cost DIY Flow Battery test system 

Optional Accessory

· For a convenient electrolyte delivery to the flow cell, the anti-corrosive tanks feature easy tube connectors and can be seated onto a jig to prevent from falling over. Please click here to learn more on the product page
