Electrolyser System Test
Test 22.06.22 (Hydaulic Test of pipes)
Test 1.2.26 with Anion Exchage Mebrane (AEM)
Problem Description:
During operation of the electrolyzer system, the gas bubbles were observed in the hydrogen chamber are very weak and
oxygen chambers didn't release any bubbles. This indicated that the electrolysis process was not occurring properly and the
system was not producing hydrogen or oxygen.
The following steps were taken to fix the system:
1. The electrolyzer cell was opened.
2. The old membrane was removed and found to be damaged (punctured) and replaced with a new one.
3. The electrical electrodes were inspected and were found to be loose so they were tightened properly to improve electrical contact and reduce contact resistance.
4. The cell was reassembled and checked for mechanical and electrical stability.
Repair Result
- The current increased significantly (from about 1.7 A to around 15 A).
- Electrolysis started normally.
- Hydrogen and oxygen bubbles appeared clearly in the gas chambers.
System Operation Procedure
A) System Startup Using GUI
1. Open the control software GUI.
2. Manually turn ON all valves and pumps in the system.
3. Verify that all pumps and valves are operating correctly.
4. Switch the system to Automatic Mode.
5. Confirm that the level sensors indicate the correct (High) status.
B) Electrolyzer Operation and Gas Verification
6. Start the system (the power supply is part of the system operation).
7. Set the operating point so the current is not at the minimum level (typically around 4–5 A).
8. Observe the electrolyzer chambers and confirm the formation of bubbles for both hydrogen and
oxygen.
9. The gas chambers are connected directly to a burner/igniter.
10. As gas flows, it is continuously burned so that gas does not accumulate.
11. Mini pops during combustion confirm hydrogen and oxygen production.
