Starting to bust water into its basic elements

The basic electrolyser design is finally finished. After a lot of steel cutting and drilling, I've finally finished the first prototype of the machine which will tell wether or not pulsed electrolysis of the water, through special frequency and pulse duration control, can by itself be the key to making the process several times more efficient than conventional DC electrolysis.

For now there are a few issues to resolve, namely:

• Make the seal on the top cover air tight - even though the container was bought under the premise that it would be air tight, in practice is was verified that it was not;


• Control circuit FET transistor is heating up too much under a 4 Amps load - must check if the gate voltage is being enough to cause it to switch from cutoff to saturation and not somewhere in between. According to the device datasheet, it dissipates up to 150 Watts of power. In this case it has to dissipate around 40-50 Watts of power (10 to 12 Volts at 4 Amps), which is probably too much for the 25 cm^2 heat sink installed.

This is the complete setup (electrolyser + control unit + DC power supply):




4 Amp run (12 V):


No load applied:
