Is the H-Series the Right PEM Electrolyzer for Your Project?
The H-Series is designed for buyers who have moved beyond small laboratory hydrogen generation and need a more stable mid-range PEM electrolyzer system for on-site use, pilot production, or early industrial hydrogen supply.
Best Fit For
- • On-site hydrogen supply
- • Pilot industrial hydrogen projects
- • Microgrid hydrogen systems
- • Semiconductor-related hydrogen applications
- • R&D scale-up projects
- • Small industrial hydrogen generation
- • Continuous or scheduled hydrogen production
- • Customers moving from lab testing to practical hydrogen use
Not Ideal For
- • Very small laboratory or education-only systems
- • Large industrial continuous hydrogen demand above 10 Nm³/h
- • Utility-scale hydrogen production
- • Large refueling station hydrogen supply
- • Outdoor rapid deployment requiring containerized layout

Engineering Note
If your project requires less than 1 Nm³/h hydrogen output, the S-Series may be more suitable. If your project requires more than 10 Nm³/h or full industrial continuous hydrogen production, the C-Series, M-Series, or Containerized PEM Electrolyzer may be a better fit.
H-Series Capacity & Configuration Overview
The H-Series provides a mid-range PEM electrolyzer platform for projects requiring higher hydrogen output than compact lab systems, while still maintaining flexible skid-mounted integration. Final configuration should be reviewed according to hydrogen output, purity target, outlet pressure, operating hours, power supply, water quality, BoP requirements, control system, and documentation needs.

Buyer Note
For faster configuration review, please provide your required hydrogen output, operating hours, outlet pressure, purity target, power supply, water quality, downstream use, installation site, and destination country before quotation.
Mid-Range Hydrogen Production Requires Stable System Integration
A mid-range PEM electrolyzer must deliver more than higher hydrogen output. It must support stable operation, utility matching, water quality control, cooling, BoP integration, pressure management, safety protection, and project documentation.
For pilot and on-site hydrogen projects, system performance depends on how the PEM stack, power supply, water system, gas-liquid separation, cooling, control logic, and downstream interface work together. Hele Titanium reviews H-Series configurations according to application, operating profile, hydrogen output, purity target, pressure requirement, utilities, safety requirements, and delivery needs.
