elektrolüüser

An elektrolüüser is a device used to perform electrolysis, a process that uses an electric current to drive an otherwise non-spontaneous chemical reaction. In its most common application, an elektrolüüser splits water (H2O) into its constituent elements, hydrogen (H2) and oxygen (O2). This process typically involves immersing two electrodes, an anode and a cathode, in an electrolyte solution and passing a direct electric current through them.

The electrolyte, which can be water itself with added ions or a specific electrolyte solution, facilitates the movement of ions and completes the electrical circuit. At the anode, oxidation occurs, releasing oxygen gas and electrons. At the cathode, reduction takes place, where electrons are consumed to produce hydrogen gas. The design and materials of the elektrolüüser are crucial for its efficiency and durability, with different types employing various electrode materials and electrolyte mediums such as alkaline, proton exchange membrane (PEM), and solid oxide technologies.

Elektrolüüser technology is gaining significant interest as a method for producing green hydrogen, particularly when powered by renewable energy sources like solar and wind. This "green hydrogen" can then be used as a clean fuel, in industrial processes, or for energy storage. The scale of elektrolüüser systems can vary from small, portable units to large industrial installations.
