Dry Claw Compressor for Fuel Cell Hydrogen Recirculation | MINK MH Series

We design and manufacture MINK MH series dry claw compressor, a purpose-built solution to solve hydrogen recirculation challenges in PEM fuel cell systems. Built for harsh and extreme operating conditions, this oil-free claw compressor ensures stable, safe hydrogen circulation for fuel cell commercial vehicles, railway, marine and stationary power generation, with full SGS-TÜV certification for hydrogen service.

Core Advantages of Our Dry Claw Hydrogen Compressor

Certified Safety for Hydrogen Applications Approved by SGS-TÜV and TÜV Saar, our dry claw compressor meets strict global safety and regulatory standards for hydrogen service. You can deploy it in fuel cell systems with full confidence, zero compliance risks.

Dry & Non-Contact Operation, Almost Maintenance-Free Adopting dry compression technology, the claw compressor runs without any lubricant or working fluid inside the compression chamber. No physical contact between internal moving parts means minimal wear, nearly zero maintenance and extra-long service life, directly cutting your operational and upkeep costs.

Reliable Performance Under Extreme Conditions With high vibration resistance and a wide operating temperature range from -30℃ to +85℃, our dry claw compressor delivers consistent output even in harsh on-road, off-grid and extreme climate environments. It is perfectly suited for heavy-duty hydrogen trucks running on complex routes and remote stationary power stations.

Compact All-In-One Design, Space-Saving The integrated structure with built-in speed control device saves valuable installation space, making it an ideal fit for space-constrained fuel cell systems in commercial vehicles. It adjusts flow rate in real time to maintain optimal working efficiency across its entire lifecycle.

Intelligent CAN Control for Easy System Integration Equipped with CAN communication system, the compressor supports real-time monitoring and adjustment of speed, power consumption and other parameters. It can be seamlessly integrated with your fuel cell management system for smarter operation.

How Dry Claw Compressor Supports Fuel Cell Operation

In a PEM fuel cell, hydrogen from storage tanks reacts with oxygen from air to generate electricity, with heat and water as only byproducts. To prevent oxygen from entering the hydrogen loop and avoid explosion risks, excess hydrogen is fed into the system - and this surplus hydrogen must be recirculated instead of being released, per emission regulations and energy efficiency requirements.

Our dry claw compressor drives this critical hydrogen recirculation process. It draws surplus hydrogen from the fuel cell anode and feeds it back to the system inlet, maximizing hydrogen utilization, improving overall fuel cell efficiency and ensuring safe, compliant operation. As a TÜV-approved hydrogen claw compressor, MINK MH is purpose-developed for this core recirculation role in fuel cell systems.

Key Applications of Dry Claw Recirculation Compressors

Transportation Applications

Our dry claw compressors are widely deployed across hydrogen-powered mobility scenarios, with a focus on commercial vehicles:

Hydrogen fuel cell commercial vehicles (heavy-duty trucks, buses, light trucks)

Railway, marine and aviation fuel cell power systems

Stationary Applications

Ideal for stationary PEM fuel cell power generation systems, providing stable hydrogen recirculation for distributed power stations and backup power facilities.
