Operating current of zero-pole distance cell
Thread Content
Dear friends from Sichuan, please share your respective operating currents for zero-pole distance slots
At present, the operating current of our company’s zero-gap cell is 14,000 A (after modification using Asahi Kasei’s high-density cells)
We are the electrolyzers from Beihua Machinery, and our operating electric density is 5.5 KA.
We use Beihua Ji electrolyzers and Asahi Kasei ion exchange membranes; the operating current is 14.5 KA, with a voltage of around 485 V
The chlorine plant electrolyzer was operated with an electric current density of 6 KA/m2, and the corrected voltage remained stable within the range of 2.90–2.95 V.
The Japanese Asahi Kasei electrolyzer has an electrical density of 5.0–5.185 KA/m2, with a voltage ranging from 3.069 to 3.085 V; the ion membrane is currently being replaced.
The tank of Beihua Machinery operates at a current of 14.85 KA
North China Chemical Machinery membrane pole distance: 14.85 KA, cell voltage: 3.0–3.4 V
What causes such a large voltage range? Is it due to the ion membrane, the electrolyzer, or operational factors?
The voltage values are quite good; they remain below 3.1V until the membrane replacement cycle is reached. What about the current efficiency?
