Hydrogen is a diatomic element that is in a gaseous form at room temperature. Its most identifying characteristic is the fact that it is highly explosive. It is the lightest element in the world, and has a lifting power of 8% more than that of helium. Hydrogen was used in airships and zeppelins for more than 20 years during the beginning of the 20th century. This practice stopped abruptly after the German airship Hindenburg disaster over New Jersey. It is used in fuel cells to create electricity, and to power cars and planes. Liquid hydrogen is mixed with liquid oxygen to form a cryogenic liquid that is burnt in Solid Rocket Boosters to power the space shuttle. Hydrogen is used to fill weather balloons because of its superb lifting power. Hydrogen forms lots of important bonds, primarily with the elements fluorine, oxygen, nitrogen, and carbon. A hydrogen acceptor is an element that accepts hydrogen atoms and is attracted to them. The most common compounds formed by hydrogen are hydrochloric acid, phosphoric acid, and water. Hydrogen bonds are also significant in the construction of synthetic materials, such as nylon, and organic materials like wood and cotton. Hydrogen also bonds with oxygen to form hydrogen peroxide (H2O2), which is a very common household oxidizer. Hydrogen peroxide is used to give white laundry a bleach-free bleaching. Mix it with backing soda for a painful toothpaste substitute. Remove wine, blood, tea, and coffee stains from most fabrics. Make a solution with water and scrub your sink!

It requires a slow start-up time to spool up to its operational temperatures, and it not very portable. There is a type of welding that utilizes hydrogen, called Atomic Hydrogen Welding. The welding tool is two tungsten steel rods, acting as electrodes, through which passes an arc of electricity. Hydrogen gas is pump through the arc, and the temperature of the arc disassociates the gas into individual molecules, which absorb an incredible amount of heat. When the gas passes through the arc, it reassembles itself, and burns ordinarily, and using oxygen in the air. This is the hottest type of welding process yet; with a flame of over 7232 degrees F. it was invented in 1926, and was used extensively in Germany during WWII.

    One of those types is the easiest type. That type would be called the MIG welding process. MIG welding process is most commonly used in fabrication shops where production is high, and the possibility of wind blowing the gas shielding away is unlikely. When it was first developed it was called Gas Metal Arc. Also known as GMAW or Gas Metal Arc Welding. The differences in the names are the type of gas used, inert gas versus non-inert gas. MIG weld welding requires three things, electricity to produce heat, an electrode to fill the joint, and shielding gas to protect the weld from the air. MIG welding is done using a very small electrode that is fed continuously, while the operator controls the amount of weld being done. In some cases when a robot takes over this process, it becomes automatic

    During the middle ages welding was very common. Early Egyptians learned the art of welding. Several of their tools were made by welding. A set of specialized workmen called blacksmiths created tools by melting the metal, then hammering them together. This method did not change much until the dawn of the 19th century which held major breakthroughs in welding. An open flame (acetylene) was very important to the history of welding. It allowed manufactures to make metal tools and equipment. In 1836 a man named Edmund Davy discovered acetylene which was soon utilized in the welding industries. Coated metal electrodes were first introduced in the 1900s. A coating of lime covered the electrode and made the weld much more stable. A number of other welding processes were also invented, such as seam welding, spot welding, flash butt welding, and projection welding. Stick welding also became popular around this time too. In the 1920s automatic welding was first introduced by P.O. Nobel. Automatic welding integrated the use of arc voltage and bare wire. It was mainly used for fixing old, molding metals. Several types of electrodes were also developed during this decade. A new type of welding was developed in the 1940s by Meredith. This became known as Heliarc Welding. Gas shielded arc welding or GTAW was another significant milestone in the welding history. Several advancements in the welding field were made in the 1960s. Dual shield, inner shield, and electro slag were some of the more important kinds developed. Plasma arc was also invented and was mainly used for metal spraying. Even now more techniques are being made. For example, laser welding was developed by the Russians and is being used more and more every day (“Welcome to

  • Benefits Of Hydrogen Fuel Cells

    713 Words  | 2 Pages

    The type of reaction that occurs within a hydrogen fuel cell is and oxidation-reduction reaction. The reaction produces electricity by oxidizing hydrogen at the anode and reducing oxygen at a cathode. The hydrogen and oxygen molecules combine to form water. The electrical current (P+) is produced by a catalyst. The oxidation reaction is: 2H2→4H+ + 4e-. The reduction reaction is: 4H+ + O2 + 4e- → 2H2O. A process that does the exact opposite thing as a hydrogen fuel cell is electrolysis. Electrolysis splits water into hydrogen molecules and oxygen molecules. The process works by using electricity to split apart the water molecule. The reaction is: H2O → H2 + ½ O2.
