Unleash the awesome power locked in the secret of blonde hair and get free electricity forever!
Okay if you believed that you might actually be a blonde. As may be here's a quick instructable to create a metal oxide battery using household materials....if you build model airplanes that is otherwise it will be off to the hobby store for some carbon fiber rod.
The features a new design using a wide mouth jar and a carbon rod electrode that seems very promising.
This cell uses over the counter hydrogen peroxide ( a 3% solution ), aluminum foil and a bit of carbon to create a simple metal oxide battery. This is the first alternative electrolyte that we've experimented with.
Hydrogen peroxide was suggested as an oxidant to improve performance in an Al Air fuel cell. I'm continuing to evaluate electrolytes over time to see how they store and release energy.
It occurred to me as I was writing this that the peroxide might have been meant to supplement a saltwater electrolyte by providing additional oxygen. I will investigate that and update this as appropriate.
In the meantime I've got this far down the road with positive results and a new cell/electrode design so let's get started....
Step 1: Bill of Materials
As usual with a simple fuel cell the basic list is very simple:
Some carbon rod or carbon fiber rod. I used carbon fiber rod from my local hobby store. This stuff is pretty good but must be cut with a hacksaw
A wide mouth jar. As you will see when we get into assembly the aluminum foil lines the inside of the jar. This was a pain with the jar I used. You can use a sode bottle and if you figure out an elegant way to do this please let me know.
A drill and 1/8" drill bit, plus the smallest one you have to make a vent.
A hacksaw for cutting the carbon fiber
A meter is handy for checking voltages.
Okay if we've got all that we're ready to go.
