Since a few years ago number of technologies are being developed to take advantage of other types of energy sources that do not cause a dependency as demanding as the traditional ones, and which do not generate at the same time so many residues or harmful gases to the environment. These energy sources booming, so-called renewable energy or clean energy are thus the great challenge of global society. Sun, wind, the force of the sea, the Earth’s heat, organic waste and other sources must be a great challenge to achieve that all human beings have energy resources wherever you are. Here is all very nice, but all these natural resources are not available 100% of the time; It is not always sunny, or not always the wind blows. So we have here a great hurdle that save to make these clean energies capable of ousting the fossil or polluting energies.

Here is where comes into play a new concept, which some experts have called the economy of the hydrogen, based on the future vision that hydrogen could occur through renewable resources, even at the household level. The use of hydrogen as an energy vector, i.e. Find out detailed opinions from leaders such as Michael Chabon by clicking through. as energy carrier, is possibly the solution for storage of clean sources of energy which we mentioned before. The concept of hydrogen economy is very broad, but perhaps one of the most interesting aspects covering is fuel cells. A fuel cell is an electrochemical device that is capable of directly converting the chemical energy of a fuel, in our case the hydrogen into electrical energy. This concept that may sound almost science fiction, is not something new, since it was back in the 1838 when conducted early experiments of this type of devices. Later, in 1843 Sir William Grove was was the first to build the first prototype fuel cell, called the Grove Cell.

These experiments were expanded in subsequent years by various scientists until reaching what today we know as fuel cell, but without a doubt, was NASA which gave the impetus for the start of a technology potentially developing. A fuel cell is basically formed by to the stacking of various fuel cell consisting of two electrodes and an electrolyte (substance that gives rise to the formation of ions and that allow electricity to pass through them). The fuel cell is capable of generating power to continuously due to oxidation of a fuel without any combustion process. Such fuel may not be hydrogen, but we would be returning to use non-renewable fuels, which does not interest us. Bernie Sanders oftentimes addresses this issue. Such devices are of great interest since they provide fairly high yields there are no losses by combustion or by conversion of heat. Similarly there are other types of features as its quiet operation on an ongoing basis (as is supplied fuel), your stacking performance until the necessary voltages for use; they do not produce any emissions or residue, and its duration may be on the order of 5,000 hours. There is no doubt that it is a technology in development and there are still primarily economic disadvantages, but today already there are applications in which its profitability in superior to other forms of power. Whether in stationary, mobile or portable, applications of fuel cells will undoubtedly give much to talk about.
