Product description

Our electrolyzers use proton-exchange membranes (PEM) to separate the hydrogen and oxygen simultaneously produced by passing direct electrical current through aqueous solutions:
These electrolyzers are used for a wide range of hydrogen applications ranging from the on-site production of carrier gases for analytical appllications to vehicle refueling stations to regenerative fuel cells.
While researchers are exploring means of splitting water by high temperature alone (the sulfur iodine process), or by combinations of heat and electric power (such as the hybrid sulfur process or high temperature steam electrolysis), only water electrolysis is a proven means of doing so. PEM electrolyzers offer smaller, cleaner and more reliable systems than competing electrolysis systems. Alkaline electrolyzers have, until recently, been less expensive due to the high precious metal requirements of a PEM cell stack, but recently Giner has demonstrated long-lived PEM cells at just ¼ of previous platinum loads and is targeting a further 33% precious metal reduction. That will render platinum costs to minimal levels.
