The electric car has been around since the 1830s, eventually transitioning to a practical transportation choice in the late 1800s after improvements in the storage capacity of batteries. The electric car was at the peak of its popularity in the early 1990s. However, its popularity was short-lived; by 1935 the electric car had become a rarity, being replaced by the gas-powered vehicles. Reasons for the change being that the electric car could not travel long distances without recharging due to the limited storage capacities of batteries, it was faster to fuel a gas car than recharge an electric car, and finally, the mass production of the gas car lowered its price significantly compared to the electric car. Present day, the conventional gas powered vehicle is still preferred over electric cars, but advances in hydrogen fuel cell technology are making the option of owning a hydrogen fuel cell powered car more of a possibility as well as highlighting the benefits of other electric cars. In the following paragraphs the operation of the Ballard fuel cell is explained, the challenges with implementing a fuel cell system is discussed and lastly, the possible social and environmental effects of electric cars are explored.
Fuel cell technology 1 Running head: FUEL CELL TECHNOLOGY: TRANSPORTATION AND RESIDENTAL/ COMMERICAL APPLICATIONS Fuel Cell Technology: Transportation and residential/commercial applications Monique University 2 A fuel cell is an electrochemical energy conversion device. A fuel cell converts the chemicals hydrogen and oxygen into water, and in the process it produces electricity. With a fuel cell, chemicals constantly flow into the cell so it never goes dead as long as there is a flow of chemicals into the cell, the electricity flows out of the cell. Most fuel cells in use today use hydrogen and oxygen as the chemicals.
As the Earth becomes more developed many changes in the environment are becoming apparent. These changes are unexpected and often faced with opposition from skeptics. One of these problems is climate change, also known as global warming. Global warming is caused by the release of greenhouse gases into the atmosphere. Greenhouse gases are produced on a large scale by combustion of fossil fuels. A major contributor to greenhouse emissions is the combustion of coal, oil, and gas in power plants. Many options to fossil fuels as a source of energy have been suggested, but with increasing energy demands our society is reluctant to risk a change. Alternatives such as wind energy, nuclear power, and fuel cells have all been suggested, but all have draw backs and limitations. The focus of this paper is expanding fuel cell production of clean energy. The problem with fuel cells is that they require hydrogen to produce energy, and currently hydrogen is produced by hydrolysis of water with dirty energy. Dirty energy refers to energy that creates dangerous byproducts such as greenhouse gasses and criteria pollutants. It is said that we can never extract more energy from hydrogen than is put into it. This is true only if we use conventional methods to produce hydrogen. What if we could turn to nature to find a way for us to produce hydrogen?
Hydrogen Hydrogen is a tasteless, odorless, colorless gas. Hydrogen is found in group 1 and period 1 on the periodic table. Hydrogen is classified as a nonmetal on the periodic table. The symbol for hydrogen is represented by an H, its atomic number is 1, and its atomic weight is 1.0079. The hydrogen atom consists of one proton, which has a positive charge, and one electron, which has a negative charge.
Hydrogen is one of the most abundant elements on the earth. It can be found in the oceans as well as the atmosphere. Over the last few years, talk about the future of hydrogen power has grown from a whisper to a roar. The use of hydrogen is not just the burning of the gas, but of its use in a fuel cell. Fuel cells might be the device that causes the extinction of the internal combustion engine. A fuel cell is a device that produces electricity from a fuel and an oxidizer, a substance that combines with the fuel. The fuel and oxidizer react chemically at two separate electrodes to produce the direct electric current; These cells use hydrogen as the fuel and oxygen as the oxidizer. Hydrogen power could be the silver bullet to the current and future energy situation.
In the search engine “Google dictionary” the author announces, “Fuel cell: a cell producing an electric current directly from a chemical reaction.” Fuel cells were thought of in 1839 by Sir William Grove who was known as “Father of the Fuel Cell.” In the article “History of
Hydrogen lies in one of the copious replacements for gasoline. It is not an energy source such as oil, but an energy carrier that is produced instead of digging and finding it underground. Though replacing fossil fuels by hydrogen fuel cell is very hard and costs a great deal, for the most part, hydrogen fuel cell is a zero carbon emission fuel which highly reduces the carbon emissions that causes pandemic global warming. Hydrogen is very helpful for nature by cause of replacing fossil fuels with hydrogen fuel cells might end global warming once and for all.
Hydrogen (comes from the Greek words, hudôr (water), and gennan (generate)) is one of the simplest elements on earth. It is estimated to make up more than ninety percent of all the atoms, three quarters the mass of the universe. Hydrogen has the highest energy content of any common fuel by weight, but the lowest energy content by volume. Hydrogen is the most abundant gas and the source of all energy that we humans receive from the sun, but is not available on Earth. Our Sun, and most of our stars generate energy by fusioning hydrogen to helium. It is only available in compound form. Such as, oxygen being combined with hydrogen, making water or H2O. Or Carbon and Hydrogen combining to make Methane, or CH4. Henry Cavendish first discovered the use of Hydrogen energy, in seventeen sixty-six. Even today we use hydrogen as an energy source, because of its high efficient, non-polluting fuel that can be transported easily, and its heating and power generator that could be token to places, where it is difficult use or have electricity. Because Hydrogen cannot be found on Earth it needs to be...
Proponents of a world-scale hydrogen economy argue that hydrogen can be an environmentally cleaner source of energy to end-users, particularly in transportation applications, without the release of pollutants like particulate matter and carbon dioxide. However hydrogen continues to have technical obstacles associated with it, including storage issues, due to the fact that hydrogen has a high energy density by weight, but has a low energy density by volume when not highly compressed or liquefied.
