Anolyte Tank for MEA Electrolyzers and GDE Flow Cells

A 3-port 100 ml electrolyte reservoir supporting storage, circulation, and ventilation


Specifications | In the Box | Gallery | Related Products | Technical Support


The Ossila Anolyte Reservoir is a 100 ml tank, ideal for anolyte circulation in GDE flow cell and MEA electrolyser setups. It has a simple three-port design perfect for the anode sides lower monitoring demands such as O2 evolution and electrolyte turnover making it a vital piece of equipment in both water electrolysis and CO2RR. A pair of inlet/outlet ports provides great circulation, while the third port allows both O2 venting and occasional sampling for pH or conductivity checks.

With excellent resistant across the full pH range, this tank is useful for tracking electrolyte depletion in acidic PEM systems, or carbonate crossover effects in AEM/BPM configurations where anolyte can pick up species migrating from the cathode side.

The compact design is perfect for bench-scale runs, the three-port arrangement makes it simple to plumb and maintain the anolyte side while providing you opportunity to analyze the electrolyte degradation before it affects cell performance.

For more complicated studies, such as CO2RR and other gas-evolving cathode reactions where you need to safely vent product gas and monitor electrolyte condition in real time, our 5-port catholyte reservoir will be more suitable.
