Modular PEM water electrolysis stack for on-site hydrogen generation
Solid polymer electrolyte (SPE) water electrolysis stacks producing 70–1000+ Nml/min of hydrogen from pure water, scalable by cell count, operating at up to 0.9 MPa with compact footprint.
Problem solved
Provides compact, on-site hydrogen generation without alkaline electrolyte handling, enabling direct coupling with renewable power sources for green hydrogen production at laboratory, industrial, or mobility scales.
Application contexts
- On-site green hydrogen generation for industry
- Renewable energy storage (Power-to-Gas)
- Laboratory hydrogen supply
- Fueling station hydrogen feed
- Methanation hydrogen feed
Technical principle
PEM/SPE electrolysis using a solid polymer electrolyte membrane to split water into hydrogen and oxygen. Stacks are assembled from multiple cells (MEA + bipolar plates) in series, with cell count determining hydrogen output. Operates on deionized water (<1 μS/cm) at 3–40°C.
Typical use cases
- On-site hydrogen for industrial processes
- Power-to-Gas renewable energy storage
- Fuel cell vehicle hydrogen supply
- Laboratory-scale hydrogen production
