About this Training Course
The reliability and durability of PEM electrolysers are critical to both performance and safety. PEM electrolyser failure analysis is essential for improving system reliability, durability, and safety. Designing reliable Proton Exchange Membrane (PEM) electrolysers requires more than technical proficiency; it demands a deep understanding of how and why systems fail, together with effective mitigation strategies, analytical methods, and preventive tools.
This training is designed to equip design engineers with the knowledge and practical skills needed to understand the key components and systems of PEM electrolysers, their operating principles, and the potential issues affecting system performance and reliability. Particular emphasis is placed on understanding the mechanisms, causes, and prevention of failures, including the degradation of PEM stack components such as membranes, catalysts, and related materials. Participants will gain insight into typical failure mechanisms, including corrosion effects, scaling, polymeric degradation, material compatibility issues, and chemically induced ageing under operational conditions. The course begins by grounding participants in the fundamentals of PEM electrolyser operation before progressing to the mechanisms that most often lead to degradation or breakdown.
Through a structured programme combining theory, case studies, and practical exercises that reflect real-world engineering challenges, participants will develop a strong understanding of common failure modes, diagnostic approaches, and design strategies that enhance system robustness. The course emphasises the interaction between materials, operating conditions, and system integration, enabling engineers to anticipate risks and implement effective preventive measures early in the design process.
By the end of the training, participants will understand the technical foundations of PEM electrolyser failures from both theoretical and practical perspectives. The course provides professionals with essential tools to support sustainable innovation and continuous improvement, enabling them to safely and effectively design, install, and operate PEM electrolyser systems.
Q1. What is PEM electrolyser failure analysis?
A: PEM electrolyser failure analysis studies why a system loses performance or stops working as expected. Engineers check membranes, catalysts, seals, separator plates, and operating data. They look for the root cause of damage. As a result, they can improve safety, reliability, and system life. In addition, this process helps teams stop the same problem from happening again.
Q2. Why is failure analysis important in hydrogen systems?
A: Failure analysis helps engineers find small issues before they grow into major faults. For example, a weak membrane or worn seal can lower efficiency and raise safety risks. Because of this, early analysis supports better maintenance and better design choices. It also helps teams keep hydrogen production stable. Over time, that can reduce downtime and lower repair costs.
Q3. What are the most common failure modes in this technology?
A: Common failure modes include membrane thinning, gas crossover, catalyst decay, corrosion, seal ageing, and sensor drift. In some cases, pumps, valves, and cooling units also fail. These issues may start with dirty water, heat, pressure changes, or poor material choice. Therefore, engineers study these patterns to reduce damage and improve system life. These are common findings in PEM electrolyser failures.
Q4. What causes membrane and catalyst damage?
A: Membranes can fail because of chemical attack, repeated stress, heat, or water impurities. Likewise, catalysts can lose activity through dissolution, fouling, particle growth, or support corrosion. Harsh operating conditions often make these problems worse. So, engineers track these causes closely. That helps them improve durability, protect efficiency, and reduce performance loss.
Q5. How do engineers detect early signs of failure?
A: Engineers use both online checks and lab tests. For instance, they may use impedance testing, gas crossover checks, resistance mapping, and trend analysis. They also review sensor data during operation. After disassembly, they may use microscopy and surface tests. Together, these tools help teams find faults early and confirm the true cause. These methods support earlier failure analysis of PEM electrolysers.
Q6. How does this compare with alkaline electrolysis?
A: Both technologies face wear and damage, but the failure patterns differ. PEM systems often show issues linked to membranes, catalysts, and changing loads. In contrast, alkaline systems often focus more on liquid handling and separator behaviour. Because the risks differ, engineers also use different test methods and prevention steps for each system.
Q7. What trends are shaping the future of this field?
A: The field is moving toward smarter monitoring, better materials, and predictive maintenance. For example, new sensors can spot changes earlier. At the same time, digital tools can link operating data with fault patterns. Better membranes, catalysts, and corrosion-resistant parts may also extend system life. Therefore, failure analysis will remain important as hydrogen projects grow. This will improve PEM electrolyser failure analysis in large-scale hydrogen systems.
