Our Testing Solutions for Hydrogen Production – PEM | AEM | AEL
We implement test benches for applications in hydrogen production, including a holistic testing concept with automation technology, data acquisition, and validated test procedures.
Hydrogen production via electrolysis plays a key role in future energy systems. Electrolyzer stacks must meet the highest requirements in terms of performance, efficiency, and durability. Accordingly, the development, validation, and safeguarding of these systems are highly demanding.
We develop test benches and testing systems for electrolyzer stacks, enabling precise characterization and validation of hydrogen production systems—from the prototype phase to industrial application.
In addition to the test bench itself, we provide a holistic testing concept including automation technology, data acquisition, and validated test procedures.

Why Sonplas
is your ideal partner for hydrogen production
You achieve higher product reliability
Through intensive testing under realistic and accelerated operating conditions, potential weaknesses can be identified early and degradation mechanisms analyzed. This increases the reliability and service life of your electrolysis stacks.
Faster development cycles
Automated test programs, accelerated aging tests, and reproducible test sequences enable more efficient development processes and help bring your systems to market faster.
Proven safety of your systems
Testing under high pressures, dynamic load cycles, and controlled test environments provides reliable data to demonstrably meet the safety requirements and operating limits of your electrolysis systems.
You gain reliable data for better design decisions
Through precise measurement of current, voltage, temperature, pressure, and individual cell voltages, you gain detailed insights into the behavior of your stacks—the foundation for targeted design optimization.
Reliable testing even under extreme operating conditions
Through endurance testing, pressure cycling, accelerated stress tests, and testing up to material fatigue, your systems can be validated under realistic conditions and their long-term performance reliably ensured.
What can be tested with our test systems for PEM, AEM and AEL electrolysis stacks?
Our development test systems for PEM, AEM, and AEL electrolysis stacks are specifically designed for the precise development, characterization, and validation of stacks with an electrical power output of up to 200 kW.
The test systems enable highly accurate control and continuous monitoring of all relevant operating parameters, such as current, voltage, temperature, and pressure. Thanks to full automation, complex test sequences, long-term endurance tests, and accelerated aging tests can be carried out reliably and reproducibly.
Precise measurement data provide the foundation for optimizing performance, efficiency, and service life of PEM electrolyzer stacks.
With Sonplas electrolyzer stack test systems, you create the basis for reliable development decisions, accelerated product maturity, and maximum operational reliability of your electrolysis systems – for your success.

What are the benefits
of our specialized test systems for electrolysis stacks?
Electrolyzer stacks must withstand high levels of stress. Our test systems simulate realistic pressure loads, dynamic load cycles, long-term endurance tests, accelerated stress tests, and testing up to material- and function-related fatigue.
Targeted overload and stress scenarios enable the early identification of weak points, detailed analysis of degradation mechanisms, and reliable lifetime assessments.
How do we ensure a safe testing environment?
All tests are carried out in our specially designed, ATEX-certified thermal chambers, ensuring the highest safety standards.
They provide a controlled and safe environment for testing under elevated pressures and demanding thermal conditions.
The thermal chambers ensure:
- Maximum safety standards for high-pressure applications
- Controlled temperature management for reproducible results
- Shielded test areas for critical load scenarios
- Precise data acquisition and continuous monitoring
This creates the basis for reliable and reproducible results – even under extreme operating conditions.

We develop PEM electrolysis stacks. Why are precise test systems for PEM electrolysis stacks so important?
PEM electrolyzer stacks must meet the highest requirements in terms of efficiency, performance, and service life. Only reproducible testing under realistic and even intensified conditions provides the data needed for reliable development and targeted optimization of your systems.
Our test systems enable precise control and monitoring of all relevant operating parameters, creating a solid and reliable basis for your development decisions – for your success.
We want to comprehensively test our stacks. What tests are possible on Sonplas test systems?
Our test systems cover a wide range of investigations, from activation, stability, and degradation analyses to long-term endurance tests, accelerated stress tests, pressure cycling, leak testing, and electrochemical characterization.
Thanks to full automation, even complex test sequences can be executed reliably and reproducibly.
Our systems must perform reliably under a wide range of load conditions. Can this be tested realistically?
Yes. Our test systems enable testing under dynamic load cycles, high operating pressures, and across the entire performance range – from minimal partial load to maximum operation. Within the specially designed thermal chamber, even demanding stress scenarios can be carried out safely and under controlled conditions. This allows weak points to be identified at an early stage and reliable lifetime assessments to be performed.
