Q:

What is a hydrogen generator?

A:

Quick Answer

Hydrogen generators produce high purity hydrogen by a mechanism known as proton exchange membrane, or PMA, and pressure swing adsorption, or PSA, technology. Hydrogen generators are used for a variety of tasks, such as hydrogenation, materials processing and energy storage.

Full Answer

Commercially manufactured hydrogen generators sport automatic features like production control and water level control. Additionally, the machines are engineered to detect hydrogen leaks, as well as come equipped with a dew point meter, a datalog computer and an onboard deionized water system, all of which ensure the quality and safety of the hydrogen generators. In general, the hydrogen produced with its hydrogen generators is 99.9998 percent pure.

Hydrogen generators function on a mechanism called PEM. During the process, hydrogen atoms lose their electrons as they pass through a permeable sheet composed of electrolytes. Once the protons pass through the sheet, they become ionized at the end called the anode, and are then positively charged as they move toward the other side called the cathode. As the electrons move through this course, they give off electric power, which can be utilized such as with hydrogen generators. Water is produced as a byproduct of the PEM.
