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.

Do
Check packaging + damageVerify components presentInspect tubing, connectors, cell body, electrodes
Record
Date, operator name, unit condition
2. Setup Preparation (Parallel) (2 steps)
Prepare Installation Area
Stable bench, dry areaVentilation ensuredNo ignition sources nearbyPPE ready (gloves + goggles)
Prepare Log / Run Header (Optional but nice)
Use-case: demo / lab testingOperator name + dateNotes field ready
Mechanical Assembly (Cell Setup)
Fit separator (if applicable)Install electrodes correctlySeat gasket properlyTighten screws evenly (cross-tightening)
4. Filling + Connections (Parallel) (2 steps)
Prepare & Fill Electrolyte (KOH)
Prepare 20–30% Potassium Chloride solutionFill up to safe level (avoid overflow)Ensure electrodes fully submergedClose lid properly
Connect Gas Tubing + Venting (CRITICAL)
Cathode → H₂ outletAnode → O₂ outletRoute gas to safe open vent / bubblerEnsure no kinks or blockage
Electrical Connections (Power OFF)
Confirm power supply OFFConnect cables with correct polarityEnsure connections are tight & insulatedConfirm output knob at minimum / safe start
Start Operation (Controlled Run)
Turn ON power supplyStart at low settingsIncrease slowly (voltage/current gradually)Observe bubbling / gas outputMonitor temperature + leaks
Stop Immediately If
Leak occursExcess heatingUnusual smell / unstable displayTubing blocks
7. Monitoring & Logging (Parallel During Run) (2 steps)
Live Monitoring Checklist
Steady bubblingNo leakageNo overheatingVenting open
Basic Run Notes (SOP style)
Record:
Start timeSettings used (V/A)Visible output stabilityAny warning/irregularity
Shutdown + Cleaning + Storage
Switch OFF outputTurn OFF mains powerDisconnect safelyDrain electrolyte (if required)Rinse with distilled waterDry properlyStore upright & labeled
Maintenance & Routine Checks (Periodic), Limitations & Safe Use Notes
Inspect electrodes (deposit/corrosion)Check gasket conditionClean tubing blockagesReplace electrolyte as neededTightness/seal check
Notes:
Demo/lab-scale electrolysis onlyNot for pressurized storageNot for industrial hydrogen supplyNo 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.
