HYDROGEN CARS, why?

Question

.. do we need to have a hdrogen fuel station? is it to pump compressd hydrogen into the car?

i thought a hydrogen fuel cell was self sustaining

well i mean when you put water in it a smal energy souce is used to power the electrolosys process to produce hydrogen and then the enegery of hydrogen circulates as long as you have water to add

AM I NOT CORRECT? someone help me out here because i am slightly confused?

Answer 1

yes, the hydrogen fuel station is to pump hydrogen into the car.

no hydrogen fuel is not self sustaining.

there isn't any energy in water.

burning hydrogen produces energy.

in order to separate that hydrogen from the oxygen, you have to supply at least as much energy as was produced when the hydrogen burned in the first place.

all these HHO sites are not telling the truth.

you can't get energy from HHO.

it's water.

they're using a different name trying to fool you.

in your case, apparently successfully.

you have to stock up on hydrogen.

there are a very few stations in select locations.

in addition, i've been lead to believe that Honda makes a device that uses lots of electricity to produce hydrogen by electrolysis, which you can lease when you lease their car.

Answer 2

Hydrogen is not an energy source, it's a means of storing energy, sort of like a battery. You need to produce that hydrogen, with the Honda FCX there's a home refueling station that produces hydrogen from natural gas. Electrolysis can also produce hydrogen but it's very inefficient (that may soon change but for now it's inefficient). The fuel cell is therefore not self-regenerating, the hydrogen and oxygen produce electricity with water as the waste product. You need to add more hydrogen to the fuel cell and it can take oxygen from the air since it's only acting as an oxidant to aid the process. http://en.wikipedia.org/wiki/Fuel_cell

If QSI's new nano-material really does boost electrolysis efficiency to 85% then that may be more efficient than the home refueling station made by Plug Power. Their process is described at: http://www.nanowerk.com/news/newsid=4719... The current means of producing hydrogen from natural gas produces a lot of greenhouse gases, electrolysis may produce none at all if the electricity comes from renewable sources.

Answer 3

There are many different types of hydrogen powered vechicles.

One is "On board Hydrogen generation". The other is compressed hydrogen that you buy at a fueling station.

A hydrogen engine itself is not rocket science. It is just like the engine you have except that it may be optimized for hydrogen fuel efficiency.

The great question is where do you get the hydrogen. On board hydrogen generators from fuel cells are expensive and don't last long at the present state of technology.

Electrolisis or chemical generators are other types.

Manufactured hydrogen from natural gas is another option. This you would purchase from a fueling station.

One thing should be kept in mind, Energy is not created or destroyed. It is transformed from one form to another.

The energy that is used to create hydrogen can never be less than the energy it produces.

Answer 4

nope. there are these processes involved, you see, hydrogen atoms doesn't come in its atom alone ots bonded with other elements so further processes should be done in order to extract hydrogen. BUT, latelyin the news i saw an inventor from the philippines powering with just water in his machine directly.

Answer 5

WRONG !!! A hydrogen fuel cell wants hydrogen and oxygen already separated. It is expensive in energy to convert water to hydrogen and oxygen. Very inefficient. The Loss is over 40%.
