Hydrogen Applications: Select by Duty, Not by Catalogue

Start with what the gas has to do — carrier, fuel, reaction gas or process feed — then with how much of it is needed at the same time. Flow, duty cycle, required gas quality and the delivery point decide the configuration. This page routes you to the application closest to your project.

Project scope

Find the right equipment pathway

Compare PEM systems within the published 0.5–200 Nm³/h range. Laboratory instruments, OEM stacks and teaching equipment have separate product specifications; application demand is not a promise that every flow is a standard system size.
01 · Production gas
Start with simultaneous demand and operating hours.
02 · Laboratory
Check the instrument model and gas specification.
03 · OEM integration
Define who supplies power, water, cooling and controls.
04 · Teaching
Choose an educational kit by learning objectives, not plant output.
Purpose & value

Three questions decide the system before price is discussed

Most specification errors trace back to answering these three loosely. Answering them precisely is what makes the quotation comparable between suppliers.

01 · How much gas, at the same time?

Not the daily average. Concurrent peak demand across every consumer on the header sets the capacity, and it is the number most often underestimated.

02 · What quality, at the delivery point?

The receiving instrument or process sets the moisture and impurity limits. A headline purity percentage measured at the generator outlet does not answer this.

03 · What happens when it is serviced?

Availability is a design input, not a maintenance detail. Stating the target uptime determines whether redundancy belongs in the configuration.
Note on the figures on this page. Output, pressure and purity values describe reference ranges, not every simultaneous operating point. Final technical values, documentation and delivery terms belong in the approved quotation.

Buyer questions

Questions before specification

How do I choose between a laboratory and an industrial hydrogen system?

The split is set by gas demand and duty cycle, not by the label. Laboratory duty is defined by instrument flow, often tens of millilitres to a few litres per minute with intermittent operation. Industrial duty is defined by concurrent peak demand across a plant header, continuous operation and a stated availability target.
The series describe output range and packaging. Compact units cover low flows for laboratory and pilot duty, mid-range systems cover small industrial skids, and larger or containerised systems serve plant-scale and multi-module installations. Final selection is confirmed against your flow, pressure, purity and duty cycle.
No. The required gas quality is set by the receiving process or instrument, and it must be defined at the delivery point rather than at the generator outlet. Moisture and individual impurity limits, not a single headline percentage, are what determine the gas treatment scope.
Yes, provided the shared header is specified for the combined peak demand and the gas quality meets the most demanding consumer. Where consumers need different purity or pressure, separate branches or separate systems are usually more practical.
Each application page lists the reference configuration, and the datasheet requests show the equipment boundaries. The approved technical specification with the quotation defines the supplied scope.
