Internship | Influence of Impurities on Anion Exchange Membrane Water Electrolys

As industries shift toward decarbonization, green hydrogen offers a clean alternative to fossil fuels, as it is produced via water electrolysis using renewable electricity. TNO is investigating a wide range of materials, from membranes to electrocatalysts, to prepare all electrolysis technologies for scaleup to be able to meet the 100+ GW green hydrogen production capacity required for the energy transition. Anion Exchange Membrane (AEM) electrolysis is a promising emerging technology that combines the cost benefits of alkaline systems with the efficiency of PEM systems. Their high pH environment enable AEM electrolyzers to use non-precious metal catalysts, while maintaining high differential pressures.

This internship focuses on investigating the durability of AEM electrolyzers, specifically how impurities and stressors affect membrane and electrode lifetimes, contributing to the development of scalable and durable components. For 5-6 months (can be longer if desired), you will dive into hands-on experimental research to investigate the influence of stressors on the degradation mechanisms of anion exchange membranes and catalyst layers. Additionally, you will have the opportunity to explore and contribute to innovative solutions that can enhance the performance and stability of this technology.

In the Faraday lab you will be able to evaluate AEM electrolyzers electrochemically under different conditions and have access to a variety of characterization techniques to better understand the degradation processes. Here you will collaborate with a team of young and driven colleagues that all have their own expertise varying from electrochemistry to material science.

Tasks include the following:

• Literature screening to understand the degradation mechanisms.
• Propose and investigate innovative component/material design.
• Conduct experimental work which includes electrochemical characterization in a 3-electrode electrochemical cell.
• Validation of an AEM electrolysis flowcell.
• Data analysis and evaluation of all experimental data.

We are looking for a social master student that enjoys laboratory work, can independently conceptualize and wrap-up a study, and is not afraid to ask for help.

What we are looking for:

• MSc student (registered in the Netherlands at the start of the internship) in chemistry, electrochemistry, chemical engineering, material science or related field.
• Ability to work independently and as part of a team.
• Highly motivated with a problem-solving mindset.
• Practical laboratory experience (please elaborate in your cover letter).
• Affinity with electrochemistry is desirable but not mandatory.

You want an internship opportunity on the precursor of your career; an internship gives you an opportunity to take a good look at your prospective future employer. TNO goes a step further. It’s not just looking that interests us; you and your knowledge are essential to our innovation. That’s why we attach a great deal of value to your personal and professional development.

After the first CV selection, the application process will be conducted by the concerning department. TNO will provide a suitable internship agreement. If you have any questions about this vacancy, you can contact the contact person mentioned below.

For this internship vacancy it is required that the AIVD issues a security clearance (VGB) after conducting a security screening. Take into account that this process may take about 8 weeks. If you have been abroad for more than 6 consecutive months, or if you do not have the Dutch nationality, it may take longer. Read more about security screening on the AIVD website.

Important to be aware of before applying:

• Before the start of the internship, the internship agreement from TNO needs to be signed. For students at a college or university based in the Netherlands, TNO uses the UNL-template (supplemented with a number of specific agreements from TNO). For students of foreign and MBO educational institutions, the TNO internship agreement applies. TNO does not sign any other internship agreements.
• Before the start of the internship, the educational institution will need to confirm in writing that:
  • 1) you are enrolled at the educational institution during the internship, and;
  • 2) the internship takes place as part of the programme of the study.
• The confirmation of educational institution takes place by signing the UNL template or forms prepared by TNO.
• Interns at TNO must be in possession of a Dutch residential address at the start of the internship. Performance of internship activities from abroad is not possible.
