MY CELLS PRODUCED 1.3V EACH AND I CONNECTED THEM IN SERIES AND I TRIED TO LIGHT A 1.5V AND STILL I CANT LET IT LIGHT? Answered

WHY CANT I LIGHT A BULB USING THIS ALUMINUM AIR FUEL CELL?

Just because you produce a voltage potential doesn't mean that voltage have the ability to supply enough current to do much useful with it.

I see you posted twice, 2 minutes apart on that instructable also. You're probably best to not use CAPS-LOCK as it looks as if you're yelling.

Perhaps the author can provide more details, but I have a hunch the real reason they are not commonly used is because of how LITTLE energy is actually available. I bet it would run a clock...

I used bleach instead of NaOH as electrolyte, is it ok?

don't see why not...you're still not going to get much/any current; again, generating a voltage doesn't mean useful power is generated.

What type of bulb are you trying to light? I'm guessing you don't have enough current. How many cells do you need a 2x2 parallel series array would effectively double both the voltage and current. Before you build more though you should measure the current.

I have no idea, probably a better question to ask the person who wrote the guide you followed. You need to hook the individual cells up to a multimeter and see how much voltage and current they can produce.
