Hydrogen Fuel Cell Environment Friendly


It is no doubt that the development of hydrogen fuel cells as an alternative fuel is good environment, but how does it work? It is easy to say that we use hydrogen technology to protect our environment and global warming.
Finding facts about it and embracing those facts can be two very different things.
First, consider the fact that hydrogen fuel cells are good for environment because they are developed the cleanest burning fuels ever.
Hydrogen is taken out of water and then put into fuel cells as a gas that can power a vehicle.
Single issue, which is a fuel cell vehicle with water vapor.
It's like having a humidifier for the whole world.

There are, however, some drawbacks that are associated with hydrogen fuel cells and the environment.
A fully efficient production, storage and transport of hydrogen should, in principle, to achieve zero emissions of undesirable gases.

But the researchers point out that such a system would be expensive, and that in reality around 10-20% of the hydrogen would escape into the atmosphere.
They say that to double when all of today's hydrogen fuel cell technologies replaces oil and gas firing on the basis of these losses or even triple total hydrogen in the atmosphere, deposited in the earth's surface.


Other researchers say that the hydrogen would be oxidized when it reaches the stratosphere, which would cool the stratosphere and create more clouds.
This delayed the breaking of the polar vortex, the north and south poles, so that the holes in the ozone layer larger and longer-lasting.
They estimate that the extra hydrogen will lead to a 5-8% rise in ozone depletion at the North Pole and between 3 and 7% at the South Pole.
The exact extent of this additional reduction of ozone, however, depends on a number of unknowns.
In addition to uncertainty over the extent of hydrogen emissions in the future, little is understood about how soil absorbs hydrogen from the atmosphere.
The researchers say that it is possible that this process could compensate for all new anthropogenic emissions.

The truth is, however, that using hydrogen fuel cells as an alternative fuel is actually - in the long run - good for the environment.
If only emission that comes from hydrogen fuel cells is water vapor, you're talking about a huge advantage over the toxic elements released into the air with gasoline burning cars.

The bottom line is that hydrogen fuel cells have a positive effect on the environment.
There are many other advantages and disadvantages of hydrogen as an alternative fuel has the most promise over any other alternative fuel.
