Diy Fuel Cell help

[thescreensavers]

I found this link for a saline (NaCl) fuel cell they applied 4.5 volts and it showed 1.88 volts when they removed the battery.

Is there anyway I could get it to make the fuel cell produce 6volts after electrolysis? different compound mixture? More Voltage applied to the water?

platinum is kindda expensive.

first of all sorry, I have no idea about it so I can be of no help.
But I am curious, isnt fuel cell supposed to produce electricity? work like a battery? why the heck do you need a 4.5v battery to create fuel cell...

looks like a lot is lost in portuguese-> english translation

Materials

Voltmeter.
Four strings with crocodiles.
Two glasses.
Spoon.
4.5 V Battery.

:awe:
that sounds dangerous

hahaha ... alligator clip leads 😀

Thinking back to chem 2 (its been a long, long time) makes me think you'll either have to change concentrations or else hook up a few cells in series.

Fuel cell is kinda like a battery. So you need to give it energy before it can give away energy. Thus, you need to produce Hydrogen before you can use it as a battery.

By the way, just a wild guess but more platinum would probably do the trick. Also with solid reagents, if you can stir the reactor, it will probably help increase the reaction rate. As I said, just a wild guess.
