Cost Competitive Hydrogen Electrolyser Stacks for Electrolyser Developers and Fuel Cell System Integrators

Acta Energy’s electrolyser stacks produce dry, pure and compressed hydrogen at 30 bar. Innovative technology, using an anionic solid polymeric membrane, patented by ACTA, allows the combination of quality hydrogen production with costs competitive to those of liquid electrolyte electrolysers. The Acta’s stacks can be used in electrolysers for the distributed generation of hydrogen for domestic, industrial and vehicle applications use, combined directly with intermittent renewable energy (wind and solar). The capacities available are 100, 200, 500 and 1000sL/h.
