How Do Fuel Cells Work?

12/11/2009 10:00 PM

I am interested in using fuel cells to create a powertrain that never needs refueled. Please describe, in detail, how a fuel cell works, how much fuel it uses, how much water is needed to cool it, how well it endures cold temperatures, how long it takes to start generating energy, how well it endures hot temperatures, and its average life expectancy.

"I am interested in using fuel cells to create a powertrain that never needs refueled."

No such thing exists. 

The rest of your question is covered pretty thoroughly on Wikipedia -- http://en.wikipedia.org/wiki/Fuel_cell

Surely you must know that just a partial answer would require perhaps 50 pages of text and several hours of editing and/or typing.

So, you will have to do this on your own. Begin by reading this, then go here, then if you're still interested, read more.

Then come back and ask questions. Cheers.

"...that never needs refueled."

By definition a FUEL cell needs FUEL! A fuel is something that gets consumed and has to be replenished.

Hi electrolyzer,

I think you should read the links and advice of other posts.

But just as an example, A Battery is a fuel cell. That fuel cell always needs fuel to replace what is used. But if you link a battery with a solar cell, the solar cell will keep the battery charged, with the small amounts of electricity from the solar cell.

A car uses the alternator which is driven by the Engine to charge the battery. Exactly the same thing is happening but from different appliances.

Nothing magic here! But, all fuels cell need the used fuel to be replaced, but if you combine a solar cell and battery, there does not seem to be anything happening, except perhaps the battery and or wires may get hot. But the sun shine on the solar cell creates electricity and it is recharging the power which has been used from the battery. It could be a torch attached to the battery or, plugged into a socket that leads from the battery which is using the power. But, it always need replacing.

Viewing sites mentioned by others and or researched by yourself will give you a much better understanding of how this 'powertrain' works, and you can see the various different ways power can be created to charge a battery or a complete row of batteries. And also why different sizes of batteries are needed for different uses.

Take care and good luck.

Take a look and study what you write from these sites. Design your own fuel cell later (in theory) and see how big it would need to be to power something you know well, like a car, bike, mower etc.

Hi ky,

That was going to be a secret.................. Now you have told the whole world. My 'marketing strategy' up in smoke! I dunno!

I appreciate the GA, thank you and hope you are well!

Take care

Hey Electrolyzer, I see in your Bio., that your still in High School. Nothing wrong with that and more power to you for finding this forum. I wish the Internet was around when I was in HS. But back to your question, as previous posted, it would take a ream of paper to go into the subject. In your Bio. you state that you want to build a car that does not require refueling. When I was in HS, we called it perpetual motion. And this has been a subject of great interest to man kind since the wheel was invented. If you or anybody else can come up with the Quantum theory to over come the natural physics of gravity, the world would be at your feet. Keep up the research and questions and maybe you just might be the person to make the break through.

Good Luck to you my friend. ∞
