With the rest of the city in darkness, superclean micropower plants carried on unaffected. The products of the reaction in the cell are water, electricity, and heat. A battery carries only so much charge and as such has a limited range. Many forms of fuel release particulates that lead to acidic rain, breathing problems, and other health concerns. It can also be stored at moderate temperatures and pressures in a tank containing a metal-hydride absorber or carbon absorber, though these are currently very expensive. Since it is considered the simplest elements, its supply in the atmosphere is abundant. Due to the high energetic content of hydrogen and high efficiency of fuel cells 55% , this great technology can be used in many applications like transport cars, buses, forklifts, etc and backup power to produce electricity during a failure of the electricity grid.

Basically, hydrogen gas is used as the main fuel source. However, it requires that a noble-metal catalyst typically platinum be used to separate the hydrogen's electrons and protons, adding to system cost. So there are research going on to see the availability of other materials. The development of low-cost materials with high durability at cell operating temperatures is the key technical challenge facing this technology. With gasoline, the base fossil fuel that is used to create it is crude oil. Unless new methods of funneling heat away from the fuel cells are developed, there may be some options that never get to experience the benefits of what hydrogen could provide. In fact, when fueled with pure hydrogen, the only by-products are heat and water, making this a source.

Indeed, if you live in the Los Angeles area, stop by one of the fuel cell car dealerships like Toyota of Santa Monica and take a hydrogen car for a spin. It can target power to where it is needed. The most abundant element in the Universe Forget the days of deep-sea drilling for oil and gas or asteroid mining for raw materials. In applications designed to capture and utilize the system's waste heat co-generation , overall fuel use efficiencies could top 85%. Lack of proper infrastructure in the form of recharging stations also stunts the growth of fuel cell vehicles. When it comes to disadvantages, fuel cells are generally expensive to manufacture. If the fuel cells were large enough, the facility could supplement the local power grid.

Moreover, fuel consumption is cut down to 50% with the use of fuel cells. For the average vehicle, the fuel economy that can be achieved is twice what the current gasoline fuel economies happen to be. They include types like metal hydride fuel cell, proton exchange fuel cell, alkaline fuel cells and so on. What happens if one part of that grid should fail? Although the chemical process involves burning hydrogen, it emits water, heat and other emissions but not carbon. There has never been a 10-year production for hydrogen fuel cells.

This technology is said to be the solution for a greener air and environment. The reason for these high costs is that hydrogen experiences high levels of energy loss when it is being transported in any form. In total, some gasoline fuels may contain upwards of 150 different chemicals, detergents, and other ingredients. The reality of the hydrogen fuel cell is that it can make an immediate impact on the emissions we all generate every day. That makes these fuel cells difficult to incorporate into certain technologies, including current automotive technologies. Despite being renewable, it still needs fossil fuels to be transformed to hydrogen fuel.

The electro-chemical reactions that take place in the cell are shown in the diagram to the right. While most consumers probably would prefer to have conventional electricity generated at a location far from their homes due to the noise and pollution, the benign nature of fuel cells makes them non-offensive even if placed in residential communities. Non Toxic All of the energy sources that we are currently utilizing are harmful and toxic. A fuel cell is an electrochemical energy conversion device that converts hydrogen and oxygen into electricity, heat, and water. Moreover, it can also decrease lung function.

This is also one of the reasons why hybrid cars are also costly. A fuel cell can be an attractive alternative to expensive uninterruptible power supplies, power-line filters, or energy storage systems used to condition grid electricity. It is important to clear up any confusion with terms related to energy efficient vehicles. This electrochemical reaction needs to be continuous, unlike a regular car battery which already has the necessary chemicals for generating power inside of it. By investing in local decentralized production, investment in the construction of large power transmission lines, the protection of these and other auxiliary equipment, and the maintenance of these infrastructures is spared. This classification determines the kind of electro-chemical reactions that take place in the cell, the kind of catalysts required, the temperature range in which the cell operates, the fuel required, and other factors.

NFCRC: Fuel Cells / Benefits

advantages of fuel cell

Fuel cells do not degrade over time, unlike batteries, and can, therefore, provide electricity continuously. Perhaps, with continuous research, the number of its advantages can outweigh its disadvantages. The high temperatures at which these cells operate and the corrosive electrolyte used accelerate component breakdown and corrosion, decreasing cell life. Methanol is also easier to transport and supply to the public using our current infrastructure because it is a liquid, like gasoline. Although some of the fuel cells' attributes are only valid for some applications, most advantages are more general. When the waste heat is captured and used, overall fuel efficiencies can be over 85%. This concern is also placed on liquid hydrogen.
