It has become clear to all that the search for alternatives to fossil fuels has become inevitable, especially after the rise in prices of conventional fuels, and the subsequent strikes of truck drivers in different parts of Europe.
But the scientists were far away; they were studying; to look for other sources of energy, and the governments of the developed countries cut aside part of their budget for the continuation and development of such research. The results were very satisfactory; the use of solar energy was developed; to generate electricity, As kinetic cards that can be converted into electrical energy, and replace many alternative energy sources with fossil fuels.
Some may ask here: If there are other images of energy sources, why is dependence on fossil fuels still going on?
The reason for this is that these new technologies are still expensive and not suitable for all applications as an alternative to fossil fuels. As we note that most of these technologies eventually reach electricity, and although electricity is widely used today, it has not yet On all fossil fuel applications, particularly bio-energy such as motor and truck management, and most of these new sources of energy depend on certain climatic and geographic conditions such as long-term solar brightness for solar energy and near-sea presence of tide, tide and wave activity.
Amidst the challenges for scientists to search for the fuel of the new future, fuel cells are once again being replaced as a global alternative instead of fossil fuels. As research continues to develop, results show that it will become the fuel of the new future.
Fuel cells are a picture of the transformation of chemical energy stored in hydrocarbons into electrical energy directly.
The fuel used in these cells is either hydrogen, natural gas or methanol using oxygen or air.
Hydrogen applications are the most widely used applications, which can be obtained from electrolysis of water.
The idea of working the fuel cell depends on the existence of a membrane membrane of iron surface coated with a catalyst (platinum) of platinum When the entry of hydrogen ((H2) works on the separation of platinum to protons and electrons and allows the membrane separates the passage of protons The electrons, which can only be traversed by a wire around the separating membrane, are allowed to pass through the wire. A flow of electrons is generated in the wire, and a constant current of DC is obtained. On the opposite side of the membrane, the electron combines with the proton again, (H2O) and heat.
It is worth mentioning here that we get electricity mostly from water, either from waterfalls like in the high dam in Egypt or from steam stations, and we get hydrogen from water and electricity together by electrolysis of water, then using fuel cells we get hydrogen on electricity and water again , A semi-closed and renewable cycle; because the main source is water and can not be destroyed or terminated like fossil fuels.
Fuel cells are also a kind of storage energy, as they begin to use electricity in electrical analysis and end up with electricity.
In the practical experimentation of the fuel cells, it was found that the products consist of some NOx and SOX, which are very harmful oxides, and to overcome it, the compounds of these oxides can be installed with the cell.
