Proton-exchange membrane fuel cells (PEMFC), also known as polymer electrolyte membrane (PEM) fuel cells, are a type of fuel cell being developed mainly for transport applications, as well as for stationary fuel-cell applications and portable fuel-cell applications.Their distinguishing features include lower temperature/pressure ranges (50 to 100 °C) and a special proton-conducting polymer. An ever-increasing dependence on green energy has brought on a renewed interest in polymer electrolyte membrane (PEM) electrolysis as a viable solution for hydrogen production. While alkaline water electrolyzers have been used in the production of hydrogen for many years, there are certain advantages associated with PEM electrolysis and its releva The PEM electrolyser system is less complex which leaves more electricity for the electrolysis process. The electrolysis itself is slightly less efficient and the main disadvantage is the use of expensive materials such as platinum.

A solid oxide electrolyzer cell (SOEC) is a solid oxide fuel cell that runs in regenerative mode to achieve the electrolysis of water (and/or carbon dioxide) by using a solid oxide, or ceramic, electrolyte to produce hydrogen gas (and/or carbon monoxide) and oxygen.The production of pure hydrogen is compelling because it is a clean fuel that can be stored easily, thus making it a potential. Purchase PEM Water Electrolysis, Volume 1 - 1st Edition. Print Book & E-Book. ISBN 9780128111451, 978012811146 PEM water electrolysis simply splits pure deionized water (H 2 O) into its constituent parts, hydrogen (H 2) and oxygen (O 2), on either side of this membrane. When a DC voltage is applied to the electrolyzer, water fed to the anode, or oxygen electrode, are oxidized to oxygen and protons, while electrons are released. The protons (H + ions) pass through the PEM to the cathode, or hydrogen. High-pressure electrolysis (HPE) is the electrolysis of water by decomposition of water (H 2 O) into oxygen (O 2) and hydrogen gas (H 2) due to the passing of an electric current through the water.
