Protocol
Operation & Standard Use of Hydrocell Hydrogen Generator
Basic Information
This SOP provides a safe and repeatable procedure for setting up, operating, and shutting down the HydroCell alkaline electrolysis unit for hydrogen generation demo/lab use.
Instrument SOP
Keywords
Materials
- Potassium Chloride
Methods (Protocol, 3 groups and 6 steps)
Receipt + Visual Inspection
Do
- Check packaging + damage
- Verify components present
- Inspect tubing, connectors, cell body, electrodes
Record
- Date, operator name, unit condition
2. Setup Preparation (Parallel) (2 steps)
Prepare Installation Area
- Stable bench, dry area
- Ventilation ensured
- No ignition sources nearby
- PPE ready (gloves + goggles)
Prepare Log / Run Header (Optional but nice)
- Use-case: demo / lab testing
- Operator name + date
- Notes field ready
Mechanical Assembly (Cell Setup)
- Fit separator (if applicable)
- Install electrodes correctly
- Seat gasket properly
- Tighten screws evenly (cross-tightening)
4. Filling + Connections (Parallel) (2 steps)
Prepare & Fill Electrolyte (KOH)
- Prepare 20–30% Potassium Chloride solution
- Fill up to safe level (avoid overflow)
- Ensure electrodes fully submerged
- Close lid properly
Connect Gas Tubing + Venting (CRITICAL)
- Cathode → H₂ outlet
- Anode → O₂ outlet
- Route gas to safe open vent / bubbler
- Ensure no kinks or blockage
Electrical Connections (Power OFF)
- Confirm power supply OFF
- Connect cables with correct polarity
- Ensure connections are tight & insulated
- Confirm output knob at minimum / safe start
Start Operation (Controlled Run)
- Turn ON power supply
- Start at low settings
- Increase slowly (voltage/current gradually)
- Observe bubbling / gas output
- Monitor temperature + leaks
Stop Immediately If
- Leak occurs
- Excess heating
- Unusual smell / unstable display
- Tubing blocks
7. Monitoring & Logging (Parallel During Run) (2 steps)
Live Monitoring Checklist
- Steady bubbling
- No leakage
- No overheating
- Venting open
Basic Run Notes (SOP style)
Record:
- Start time
- Settings used (V/A)
- Visible output stability
- Any warning/irregularity
Shutdown + Cleaning + Storage
- Switch OFF output
- Turn OFF mains power
- Disconnect safely
- Drain electrolyte (if required)
- Rinse with distilled water
- Dry properly
- Store upright & labeled
Maintenance & Routine Checks (Periodic), Limitations & Safe Use Notes
- Inspect electrodes (deposit/corrosion)
- Check gasket condition
- Clean tubing blockages
- Replace electrolyte as needed
- Tightness/seal check
Notes:
- Demo/lab-scale electrolysis only
- Not for pressurized storage
- Not for industrial hydrogen supply
- No purity guarantee in this SOP
Figure 1 . HydroCell setup for alkaline electrolysis: the acrylic cell with sealed lid and electrodes, DC power connections (polarity checked with power OFF).
This image illustrates the standard operating configuration of the HydroCell unit prior to powering ON: (i) cell assembled with gasket and evenly tightened fasteners, (ii) electrodes submerged in electrolyte, (iii) outlet tubing connected and kept unblocked for safe gas release, and (iv) electrical connections prepared with output at minimum before ramping.
Conclusion
Following this SOP ensures HydroCell is operated in a safe, repeatable, and controlled manner, with proper electrolyte handling, venting, operation monitoring, and safe shutdown/maintenance.
