101 Plate Dry Cell


Are you interested in a Big one? Do you want to take Electrolysis to the next level?
Well welcome to the Bob Boyce way.

First of all, what kind of voltage do we need to power 101 plates? I ran a configuration and here is what I came up with:

Using 220 Volts DC as a power source, 101 plates will provide 2.2 volts across each water cell. That is efficiency.
Of course,

Second; how much HHO gas can this monster make? Here is what my configurator predicts:


Why 6 inch plates? We are talking 220 volts here. We are going to need an AC power source and convert it to DC power; rectify it. Lets go easy on our utility bill for now. Also keep in mind, our power source may be coming from an Inverter that is powered by a 12 or 24 volt system. 6 inch plates have enough surface area to handle up to 18 Amps without creating excess heat. Safely put this puppy on 20 amp circuit breakers. It is the number of plates that increases our HHO production, not the size of them. Size more or less regulates the heat.

My calculations show that 1 amp will draw 220 watts from our power source, and it will produce 1061 ML or 1.016 LPM. That equates to 10.16 ML of HHO per water cell, per amp. Not bad.

How close are my calculations? Well, Hydrogen Garage sells these, and they predict it produces 10 to 15+ LPM.

What could this monster be used for?

  • Diesel Trucks

  • RV's

  • Water Welders & Torches

  • Stationary Generators

  • Home Heating

(you really should power this Cell from your AC Mains)

Scarecrow 101 Plate Dry Cell


  101 plates 6x6 Dry Cell HHO Generator, with 220v ac, 318vdc power supply, approx. 5.7 LPM @5.5 amps. Capable of producing 20 LPM at 20 amps.


  Basic Assembly

Note, never touch the plate surface with your bare fingers. You will transfer oil to the plate surface. This video just provides an idea of what it takes to assemble.



Information on Inverters
  3500 Watt Inverter / 220v /15.6 amps continuous / 50 hz

  Information at Voltage Converters.com


220 Volt Power

AC Mains Power Information - I will be adding 220 VAC information
  90 Amp AC Diode Bridge Rectifier, with heat sink; 1000 volt.

You will need 1 of these if you are going to make your own power supply for 220 volt mains. AC will be rectified into DC Pulses.




Amp Controllers

Variac Transformers

This becomes your Controller; varying the voltage varies the amperage. It also varies the water cell voltage as the Output voltage changes.

These are available in different Input voltages, and Amperages, as well as phase. Use caution when ordering one. The Link I am providing is just for reference right now.

You will need a unit that uses a 220 volt Input, that can handle - probably 20 Amps Continuous Operating.
