Simple Water Electrolysis System

Collecting Hydrogen and Oxigen using only tap water, salt and two laptop charger

Step 1: Take a Little Bowl

Take a little plastic bowl and fill with salt solution

Step 2: Take Two Big Screw

Using two big screw as electrode. One as Anode and one as Cathode

Step 3: Prepair the Power Supply

The electric flows must be Direct Current (DC) remember, must be DC, AC current won't work. I use two 24v DC Adapter from computer charger connected in serial to gain the voltage to 48v with the current flow about 6 amps.

Step 4: Make the Bubbler

Using water bottle

Step 5: Collecting Hydrogen and Oxigen

The Electrode with more bubble is Hydrogen . Choose what you want to collect and then flip the bubbler over the electrode

Step 6: Test

For Hydrogen: Using lighter to test. But remember : Pure Hydrogen is flamable, but Hydrogen with Oxigen is highly explosive, the amount of hydrogen and oxigen with the ratio of 2:1 in a big bottle can blow you up, so be careful

Be careful with salt. Sodium chloride breaks down into sodium hydroxide and chlorine gas. Very dangerous stuff. Try baking soda instead, it's a lot safer.

[How-to-make it]

Oh, thank you

You just built a simple fuel cell. Using stainless steel from the electrodes yields the best of everything.

[DIY Hacks and How Tos]

Great tutorial. I always thought that it would be fun to make a hydrogen candle that runs on gas from electronisi.
