In this video we look at several electrolysis designs and their function. Check out this video's sponsor, MEL Physics! Use the promo code "nighthawk" for 50% your first set of experiments: https://melscience.com/s3p/

Most DC power supplies will work adequately well for electrolysis, the most common of which is a 12v battery charger or a car battery itself. For more control it is best to use an adjustable power supply. Here is an affiliate link where you can purchase a similar 30v 10a power supply as I use in this video: https://ebay.us/2DY3Y0

The last design shown in this video for a combined output HHO fuel cell I first stumbled on here: https://youtu.be/bIVbbqRkudw

After filming this video I realized that the plastic bottles I used for several of my designs had become quite brittle, and found research showing that hydroxide solutions are known to be quite damaging to plastics: https://www.sciencedirect.com/....topics/chemistry/env
I did not notice increased brittleness in the clear plastic container of my final split electrolysis design, but the plastic is much thicker and so it may take longer to show weakness. A suitable precaution to give the cell the longest life may be to empty it of electrolyte while in storage. A stainless steel or glass container should be able to store the hydroxide solution indefinitely.
