The history of gasoline started around the invention of internal combustion engines suitable for use in transportation applications. The so-called Otto engines were developed in Germany during the last quarter of the 19th century. The fuel for these early engines was a relatively volatile hydrocarbon obtained from coal gas.
It designs, manufactures, operates and services Direct Fuel Cell power plants, which is a type of molten carbonate fuel cell. As one of the biggest publicly traded fuel cell manufacturers in the U.S., [3] the company provides clean energy in over 50 locations all over the world. [4]
1964 – Allis-Chalmers builds a 750-watt fuel cell to power a one-man underwater research vessel. [19] 1965 – The first commercial use of a fuel cell in Project Gemini. 1965 – Allis-Chalmers builds the first fuel cell golf carts. 1966 – General Motors presents Electrovan, the world's first fuel cell automobile. [20] 1966 – Slush hydrogen.
Hydrogen is an energy carrier and can be used to store and deliver energy as needed. When used in a fuel cell, the hydrogen atom dissociates into a positively charged hydrogen ion and a negatively charged electron which is diverted to an electric load. A fuel cell can be used to power anything in much the same way that batteries are used.
Fuel-cell forklifts can work for a full 8-hour shift on a single tank of hydrogen, can be refueled in 3 minutes and have a lifetime of 8–10 years. Fuel cell-powered forklifts are often used in refrigerated warehouses as their performance is not degraded by lower temperatures. [75] In design the FC units are often made as drop-in replacements.
SOFCs are unique because negatively charged oxygen ions travel from the cathode (positive side of the fuel cell) to the anode (negative side of the fuel cell) instead of protons travelling vice versa (i.e., from the anode to the cathode), as is the case in all other types of fuel cells. Oxygen gas is fed through the cathode, where it absorbs ...
Thomas Midgley Jr. (May 18, 1889 – November 2, 1944) was an American mechanical and chemical engineer.He played a major role in developing leaded gasoline (tetraethyl lead) and some of the first chlorofluorocarbons (CFCs), better known in the United States by the brand name Freon; both products were later banned from common use due to their harmful impact on human health and the environment.
The UTC Power fuel cell system uses natural gas which is converted in a "catalytic reformer" into hydrogen, carbon dioxide, carbon monoxide, and water. The hydrogen is used to run the four fuel cell stacks to produce electricity and the power plant then converts the exhaust heat into cooling and heating, turning potential waste into usable energy.
