  • 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

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.

MID-RANGE SYSTEM ENGINEERING

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.
