Ground-Breaking Power supplies. As part of our ongoing R and D I have dedicated time into improving the power supply and control modules which power the Hydrogen generator cell.

One of the issues of any electrolysis unit for mobile units is the available voltage and to a lesser extent the available current.

Current flow is essential to produce hydrogen  gas and using Faradays laws (1832) it is easy to calculate the amount of electrical current needed to produce a given quantity of Hydrogen gas.  Some of the “experts”  on free energy sites still believe that all they need is a resonant and a low current.  My definition of these “EX SPURTS” is that they are a “Drips” under pressure , – Pressure to prove they actually know somewhat more than a “demented earthworm”.

Excuse  my irritation on free energy morons and Getting back to the essential developments of this post….Power supplies

2 electrons are required for every molecule or hydrogen gas produced and electrical current is the flow of electrons through a conductor… 22 amp of current at 13.2 volts supplies enough electrons for a maximum of 0f 4.2 Litre of Hydrogen / oxygen  gas. Any less energy than that will reduce the gas produced.

When producing a DC power supply of fixed current , we have been conditioned to use electronic components such as constant current PWM devices.  There are several faults of such devices in control o fa DC current supply

  1. The electronics of the circuit introduces an internal resistance into the electrolysis circuit which reduces the available voltage for the unit and therefore the number of available cells that can be used for generating hydrogen gas. The REDOX potential for converting water into hydrogen and oxygen is 1.23 volts.  The internal resistance of the electrolysis produces a back voltage of 0.5 volt  and at least 0.5 volt overvoltage is required per cell to sustain a reasonable current flow through the cell. This equates to at least 2.2 volt is required to generate a useful supply of hydrogen gas from an electrolysis cell.  If we are using 6 cells then  we need 6 times 2.2 volt = 13.2 volt , to generate a reasonable supply of hydrogen gas. IF we have a PWM unit that is using 2 volts due to  internal resistance, that reduces our number of usable cells to 5 and drops the system efficiency by almost 20%.        Far too great a power / energy efficiency loss
  1. The PWM units are frequency modulated devices designed for use on DC motors designed to reduce back voltage loss due to reverse inductance and lenses law. This is not a motor and pointless using a complex frequency generating circuit that uses electrical energy in pretending to reach the resonant frequency of water. – which is several  giga-hertz not kilo-hertz as produced by commercial PWM devices.
  2. The High frequency PWM circuit forces the electrolysis cell to act as a capacitor , constantly charging and discharging and introducing a resistance known as Capacitive reactance.  Capacitive reactance is an internal resistance that uses more of the available input voltage , further putting a strain   on the voltage required for the OXIDATION / REDUCTION reaction producing water.

One solution to this situation is to run DC current into the system and control the current flow simply by the solution concentration. Sounds great but problem is

  1.  as the solution warms the resistance further falls and current flow increases exponentially overloading the vehicle generator/ alternator
  2. There is no effective control of the gas volume produced
  3. The electrolyte boils and steam is not what we want
  4. Thermal runaway changes the chemical thermodynamics of the electrolysis cells and the break down

So some form of circuit is required to limit the current without introducing a load onto the already voltage sensitive circuit.

With this in mind we have developed a relatively simple circuit that limits the voltage loss, does not produce a pointless high frequency output and yet still is able to control the voltage applied to the system so as to control the current flow and not lead to excessive heating of the electrolyte .

This circuit is simple and uses a number of Power FETS and their biasing potentiometers .   Extensive lengthy testing under a variety of temperatures has shown that this simple circuit is far superior , more robust and easier to use than the common PWM and constant current power supplies commonly used .

Hydrogen fuel systems have included this development into their patented design and manufacturing process.  A great advantage of this design is that it can easily and effectively be retrofitted to older systems currently being used  using PWM power controlling devices.

Because it  is patented process the exact schematics of the units will not be released …. Enough to say ,it is a design with will be incorporated  on all  future hydrogenfuelsystems    generator systems.

Kind regards
