This was an experiment to make a AA fuel cell with house hold parts (plus platinum Wire), but it failed. In a performence test it produced an unstead 2 - 1.5 volts for 10 seconds, yet it couldn't even light up a red LED. With that said here's the AA hydrogen fuel cell!
Step 1: Materials
nut and bolt
a tube that's the size of an AA, I made one from a 5cc syringe
a bit of aluminum
