ADVANTAGES OF PEM TECHNOLOGY
ADVANTAGES OF PEM TECHNOLOGY
HYDROGEN APPLICATIONS
IN ENERGY
In the power industry, it is used to cool high-power turbine generators. Cooling of the external stationary part of the electric generator – the stator – is traditionally carried out with the help of water registers, while the rotating rotor requires gas-phase cooling.
IN ALTERNATIVE ENERGY
In alternative energy, it is used as a fuel in fuel cells – electrochemical sources of current, in which the chemical energy of hydrogen molecules is directly converted into electrical energy without using the combustion process. The most promising and sought-after application of hydrogen in alternative energy is currently as an electricity storage device.
IN FERROUS AND NON-FERROUS METALLURGY
In ferrous and non-ferrous metallurgy, it is used to obtain pure metals by reducing their oxides extracted from ore, or extracted from spent catalysts of various technological processes, for example, such as hydrotreating of oil fractions. In particular, high-purity hydrogen is essential for the production of chemically pure copper, tungsten, and molybdenum.
IN THE RADIO ENGINEERING INDUSTRY
In the radio engineering industry, it is used in the production of semiconductor devices. One of the basic processes of semiconductor technology is vapor phase epitaxy – that is, the growth of an oriented crystal on the surface of a substrate – another crystal. In the process of epitaxy, hydrogen is often used as a carrier gas.
