The Future of Automobiles: Hydrogen Fuelled Cars and How They Work!

Fuel efficiency is in! At least that’s what most car manufacturers are saying and hooking on to. After all rising environmental concerns due to the continuous depletion of non-renewable resources has led to this emerging trend to rise like never before. Needless to say, after the introduction of fuel-efficiently technology, there has been a definite exponential increase in the number of automobile users.

  • The increase is continuous and steady! And not without the consequent benefits either! Fuel-efficient cars, or, vehicles, for that matter, have two primary benefits, which are as follows:
  • They produce minimal noise, leading to a resultant decrease in sound pollution
  • Electric fuel cells are akin to batteries which for their part are run by hydrogen.
  • Hydrogen, as such is the most stable source of energy one can find, and hence these cars are long-running and economic as well.

Not surprisingly, many would, without a doubt want to have a sneak peek into the working mechanism of such cars. So, here is a little insight into the world of Green Technology that is aimed at saving the world from the much-dreaded clutches of Global Warming and environmental deterioration.

  1. What exactly are these so-called fuel cells?

Fuel cells are basically the best of both worlds. Meaning, they’re hybrids of internal combustion engines and battery operated power sources. This is because, like internal combustion engines, they use fuel taken from an inbuilt source, or a tank, for that matter.

Then, where exactly does the difference lie? The fuel cells here do not derive their power from petroleum. Instead, they depend on pressurized, or –more appropriately put- compressed hydrogen gas.But the hydrogen isn’t consumed or burnt completely.

The gas present herein is allowed to combine with oxygen, and the entire process resembles the working of a battery since it actually ends up releasing energy.Aren’t there any resultant waste products in the process? Yes, of course, there are. The only waste product, per se, is water. In fact, the water so produced is superheated, and hence is absolutely pure, and in fact, well suited to human consumption as well.

  1. What are the various types of fuel cells that are available in markets?

Here are the following primary types of fuel cells that run on hydrogen:

  • PEM fuel cells: These are currently the most favoured fuel cells available in markets
  • fuel cells: AFC-s are predominantly used in the spacecraft industry
  • Solid Oxide Fuel cells: SOFC-s are viable alternatives to AFC-s or Alkaline Fuel Cells.Microbial Fuel Cells: These cells depend on using the basic principle of microbial decomposition in their working, with the simultaneous usage of hydrogen.
  1. Where exactly do we stand in this fuel-efficient revolution?

To be very honest, despite being in vogue, and despite being the most-discussed topic for quite a long time now, fuel efficiency in vehicles still is in its evolutionary stages. However, with increasing research, we might as well be looking at nuclear-powered vehicles very soon.However, for one to have ample knowledge on how such cars must be run, and the spare parts that are required to operate them efficiently, one could always refer to
