Process Description
Brise Chemicals offers high-efficiency bipolar alkaline hydrogen electrolyzers that split high-purity De- ionzed water into hydrogen and oxygen using DC power. In our compact bipolar design, hydrogen forms at the cathode and oxygen at the anode, delivering higher efficiency and reduced internal losses. The system operates at 0–30 bar, producing pressurized hydrogen without the need for a separate compressor.
Cathode Reaction:
2 H₂O(l) + 2e⁻ → H₂(g) + 2OH⁻(aq)
Anode Reaction:
2OH⁻(aq) → ½O₂(g) + H₂O(l) + 2e⁻
Overall Reaction:
2H₂O(l) → 2H₂(g) + O₂(g)
The generated oxygen can be released or utilized, while hydrogen can be stored, compressed, or used in various clean- energy applications.
