Three ways to start.

Choose a component to integrate, or a generator to build your setup around.

75 by 75 millimeter PEM electrolysis membrane electrode assembly

Electrolysis MEAs

For compatible PEM cells and membrane evaluation. Match the assembly dimensions to your cell design.

55 × 55 · 61 × 61 · 75 × 75 mm

PEM electrolyzer stack

PEM electrolyzer stacks

The hydrogen-producing component for your own system. Power, water handling and controls are specified separately.

Published models: 150 mL/min to 20 L/min

3 liter per minute all-in-one PEM hydrogen generator

Small hydrogen generators

For setups that need more than a bare stack. Compare the equipment included with each model.

150 mL/min · 3 L/min · 7 L/min models
Explore generators ↗

Model outputs are published nominal ratings. Confirm operating conditions, gas requirements and scope of supply for your application.

Choose your configuration.

Start with the
hydrogen you need.

A flow rate is a starting point, not a complete specification. These three details make an inquiry more useful.

01
How much, and for how long?Your target hydrogen flow and daily operating hours.
02
What does your equipment need?Required pressure, purity and how the hydrogen will be used.
03
What is already in your system?Available power, water supply and the components you need.

Before you choose.

Two practical notes for comparing PEM equipment.

01

A stack or a complete generator?

Understand what each option includes and what your team still needs to provide.

02

Reading a current-density rating

Why active area and operating conditions belong beside the number.
