Fuel cells and water hydrogen for cars?

Question

I see all these inventions on U TUBE about running cars on water or other types of fuel cells, question Do they really work and why aren't manufacturer's getting into this for future cars?

Answer 1

They work, but the cost of manufacturing them is still too high for the general market... and there has to be places to buy fuel for them (hydrogen)... that don't exist at this time.

It will come in time.

Answer 2

The hydrogen generators do indeed produce hydrogen, and the engines do indeed burn it.  But the people who build and promote these devices never quite understand that this arrangement takes more energy from gasoline than it contributes in engine power, and thus the gas mileage goes down.  Some of them are crooks, some don't understand electrical theory, and others believe that if they wish hard enough it'll all come true, which it won't.

Answer 3

People keep saying that they aren't out because they don't work, but that isn't true. Because they use them in england, and the U.S. army already!

Answer 4

I'd bet you're talking about the Brown's Gas or HHO generators, if so its a con. It's been around since before the 1970's.

You hit the nail on the head when you ask why aren't manufactures putting this on a car, its because it doesn't work.

If you'd like to see the math, post and edit, but in the end you get back 20% at best of the energy you put in back out.

Answer 5

Yes, hydrogen fuel cells work.  They have been the prime supply of power on spacecraft for generations..  Yes, water is a great source of hydrogen.  The main problem is that it requires more energy to hydrolize the water into hydrogen and oxygen than can be recovered by using the hydrogen as a fuel.  This does not take into consideration the energy requirements for compressing and storing the (explosive) gas.

If you intend to use electricity in a vehicle to produce hydrogen gas from water in order to use the gas generated to produce electricity to operate the vehicle, you really need to stop and think.  Why go through all that to produce less power than you had to start with?

Solar hydrolysis on a massive scale may be the way hydrogen fuel becomes cost-effective, but that will require huge photo-voltaic arrays.

Answer 6

You are 3/4 of the way to answering your own question.

Do they work?

If the DID work manufacturers would be implementing them.

Manufacturers are NOT implementing them.

Therefore, they must not work.
