Nel - Model MC Series -PEM Electrolyser

SHARE
The MC250 and MC500 electrolysers deliver megawatt scale performance in a containerized form for easy outdoor installations. The units feature either one or two 1.25 MW stacks with a shared balance of plant, providing a reliable solution with minimal maintenance. Multiple units can be grouped together for larger hydrogen output needs. Typical applications include renewable energy storage, industrial process gas, and hydrogen fueling.
