7.5 Nm³/h Industrial PEM Electrolyzer

Introduction

This system uses PEM (Proton Exchange Membrane) technology to electrolyze purified water and produce high-purity hydrogen. It is an integrated solution including the PEM electrolyzer, DC power supply, balance-of-plant (BOP) auxiliaries, hydrogen purification system, pure water supply module, cooling module, and electrical control system.

The system supports a hydrogen production capacity of 0.5–50 Nm³/h, with hydrogen purity up to ≥99.999% (depending on configuration).

Designed for industrial operation, it offers safe and reliable performance, one-touch start/stop, stable output, high integration, and a compact footprint. With fast dynamic response, it is well suited for renewable-energy-driven hydrogen production and is widely used in distributed hydrogen production and refueling stations, off-grid PV hydrogen production, CHP applications, high-purity hydrogen supply for the semiconductor industry, laboratory hydrogen generation, and more.
