ACTA TECHNOLOGY

AEM Electrolyser Technology

The core competency of ACTA lies in their Anion Exchange Membrane (AEM) electrolyser stack technology. ACTA’s electrolyser stack combines the benefits of the relatively cheap liquid alkaline electrolyser with those of the more flexible but costly polymer electrolyte membrane (PEM) electrolyser.

As with an alkaline system, there is no need to use noble and rare metals at the electrodes, reducing the costs and making the technology feasible on a large scale for global commercialisation. Additionally, as with the PEM system, hydrogen with a high purity can be safely produced, directly compressed to beyond 30 bar, with no need for a caustic electrolyte, and powered directly by intermittent renewables.

Why is it important?

Fuel cell systems offer many operational and environmental advantages over traditional technologies such as diesel generators and batteries. However, the need to refuel or swap hydrogen cylinders is a major obstacle to fuel cell system deployment in remote locations.

A cost-efficient AEM electrolyser solves this problem by producing hydrogen fuel on-site. With the addition of renewable power and water, it thus creates a Self-Rechargeable Fuel Cell System.

This step is important for the adoption of fuel cell technology by telecom operators and other system designers, particularly in regions with unreliable grid or poor infrastructure. It allows the taking advantage of the higher efficiencies, autonomy, and reliability offered by fuel cells, while completely removing fuel distribution costs.
