Webb19 apr. 2024 · History and Origin of The Hydrogen Fuel Cell The concept of the hydrogen fuel cell can be traced back to the year 1800, when Anthony Carlisle and William Nicholson, provided a description of the process by which electricity can be used to break down water, to yield hydrogen and oxygen [ 13 ]. WebbThis article presents the results of the development of membrane-catalytic methods for obtaining purified hydrogen of various degrees of purity required for feeding high-, medium-, and low-temperature fuel cells. In order to conduct this, porous ceramic catalytic converters were obtained using self-propagating high-temperature synthesis. These …

WebbHydrogen was discovered in 1766 by British physicist Cavendish. It was by combining metals with strong acids that Cavendish noticed the formation of a gas that he called “inflammable air” because it was combustible. This extremely light gas was in fact hydrogen. He then noticed that burning it produced water vapor (steam).
