What is a hydrogen fuel cell?

The hydrogen fuel cell is a technology that converts hydrogen and oxygen to water and produces energy that can be used in other applications along the path. Currently, most lectures are about using hydrogen fuel cells in the automotive industry. If technology can be developed to the extent that it can be available, it can be a source of energy for cars for a foreseeable future. Most people are somewhat familiar with “fuel cells” of other varieties, commonly known as batteries. Batteries, although not technically referred to as fuel cell, have chemicals that produce electricity. Zinc and manganese oxide is used in alkaline batteries. However, because the batteries are close systems, the materials cannot be replaced inside. Therefore, they eventually lose the ability to produce the current and are referred to as dead. Since the materials needed to produce current, hydrogen and oxygen, it always flows into the cell, always flows from the cell. This constant regeneration is one of the great rainsHydrogen fuel cell.

hydrogen fuel cells, especially if used to power the vehicle, can be very energy efficient. In fact, most hydrogen fuel cells that use pure hydrogen have almost 65 percent in automotive applications. On the other hand, petrol -powered vehicles will lose great efficiency through a by -product of heat. When the gasoline is converted into mechanical energy, so much heat is lost that the total efficiency is approximately 20 percent.

The

hydrogen fuel cell offers a number of other advantages over a traditional vehicle powered by petrol or diesel. First, no carbon dioxide or other harmful emissions. The only by -product of the hydrogen fuel cell is water. Secondly, for those countries that do not have many sources of fossil fuels, hydrogen fuel cells are a large energy source that to operate afterIt uses virtually unlimited supplies of hydrogen and oxygen.

While there is currently technology at a level where a hydrogen fuel cell vehicle can be developed and there are even some on the road, they are still relatively expensive compared to their petrol cousins. Rare metals needed for fuel cells and the cost of other raw materials are very expensive to produce. Many scientists feel that technological progress will only make it a matter of time before these production costs begin to fall. In the meantime, however, hydrogen fuel cell vehicles are still from the price range of the vast majority of the population.
