More Than a PEM Stack: Why GT-7.5 Is Built as a Deployable Hydrogen Production System

Many hydrogen projects run into problems not because the electrolyzer cannot produce hydrogen, but because the system around the stack is incomplete—water quality is unstable, gas contains moisture, controls are not robust, or auxiliary interfaces are unclear. GT-7.5 is developed with a practical goal: deliver a PEM-based hydrogen production system that can be engineered, installed, and operated with confidence.

A complete system architecture (not just a component)

The GT-7.5 hydrogen generator integrates PEM electrolysis with supporting process modules. Depending on project scope, the solution can include:

• Electrolyzers (PEM)

• Power supply facilities, including constant-current power supply

• Pure water preparation facilities and circulation waterway design

• Gas–liquid separation facilities for hydrogen handling

• Hydrogen purification facilities (as required by use case)

• PLC control facilities, HMI/control panel, and system diagnostics

• Safety system and protection logic

• Piping, valves, separators, dryers, and other balance-of-plant components

This approach helps customers reduce on-site integration work and shortens the path from procurement to operation.

Clear control logic with PLC readiness

Industrial users expect stable start/stop sequences, reliable alarms, and traceable operation data. A PLC-based architecture supports:

• consistent operating procedures (startup, shutdown, purge/vent strategies as designed)

• monitoring and control of key parameters

• easier troubleshooting and maintenance planning

• the ability to integrate with plant-level systems (depending on interfaces)

Why system integration matters for hydrogen quality and uptime

GT-7.5’s integrated design supports:

• controlled water management (qualified DI water delivery to the electrolyzer)

• oxygen removal on the anode side via an oxygen pump

• improved gas handling through gas–water separation before pressurized hydrogen output

• a scalable engineering foundation for future upgrades (purification, drying, utilities, etc.)

If you are comparing PEM options, consider evaluating not only stack specs, but also balance-of-plant completeness, control architecture, and interface clarity.
