AEM Electrolyzer EL 2.1
DESCRIPTION: Enapter's core product is the anion exchange membrane (AEM)
electrolyzer. The stack is the electrolyzer's heart and comprises multiple cells
connected in series in a bipolar design. Enapter's unique technology is the design
and operation of these cells, consisting of a membrane electrode assemble (MEA),
made from a polymeric AEM and specially designed low-cost electrodes. The anodic
half-cell is filled with dilute KOH (alkaline) electrolyte solution; the cathodic half-cell
has no liquid and produces hydrogen from water permeating the membrane from the
anodic half-cell. Oxygen evolves from the anodic side and is transported out from the
stack through the circulating electrolyte. AEM stacks or " cores " produce hydrogen
with high pressure and purity. Simultaneously, AEM technology uses widely available
and low-cost materials, which results in significantly lower-cost hydrogen. Enapter's
patented AEM electrolyzer is a standardized and flexible system to produce onsite
hydrogen. The modular design paired with advanced software integration allows setup
in minutes and remote control and management. The electrolyzers are stackable to
achieve the required hydrogen flowrate.
ADVANTAGES/KEY FEATURES:
* Minimal use of noble metals: Widely available, low-cost materials
allow for lower-hydrogen cost
* High efficiency
* Automated and remote operation with Enapter's
Energy Management System (EMS)

* Ideal for onsite hydrogen production
* Modular design: Modules can be easily integrated in 19-in racks
* Safe operation
* Quick and easy installation
* Low maintenance requirements
* Small footprint due to compact design
