Water Fuel Cell - back to business

After reparing the WFC and adding extra safety measures, here is the entire setup producing hydrogen at 12 Volts DC and 1.94 Amps. Next I will provide a grid with measured values, including gas volume:

Water Fuel Cell - cleaning the mess and repairing the electrolyser

After yesterday's mishap, and of realizing how lucky I was to still be in one piece, it is time to take a deep breath and after looking into what went wrong, follow all the safety measures to prevent one such event from ever happening again.

I started by getting a new lid for the electrolyser and putting a new seal rubber in it, this time with two clamps instead of one. Now only the clamps are used for holding the lid. The original ring around the lid was discarded. By itself this doesn't provide extra protection against an explosion, apart from the slight probability of the lid popping out in one piece instead of fragmenting into several pieces (today I still found fragments of the lid in distant corners of the room).

Water Fuel Cell - HUGE ELECTROLYSER EXPLOSION

Sometimes mistakes can be the death of the artist. In this case I got closer to it than desirable: after building a tiny bubbler for testing sustained combustion I hooked it up to the electrolyser (aka: Water Fuel Cell) - one tube going from the electrolyser to the bubbler and another tube from the bubbler to the gas exit, where combustion would be tested.

The bubbler was working fine, air tight as necessary. After approaching the output from a flame, small explosions along the tube would occur, without affecting the WFC.
