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.
