Stage | Advanced manufacturing techniques for alkaline electrolyser electrodes

Given the significant demand for green hydrogen in the context of the energy transition, it is crucial to increase its production capacity through electrolysis in the upcoming years. Among the various electrolyzer technologies, anion-exchange membrane water electrolysis (AEMWE) stands out for its potential to enable low-cost, green hydrogen production, as it does not depend on precious metal materials as catalysts. To fully capitalize on this promise, the advancement of high-performance electrodes emerges as a critical factor. This project aims to further advance the manufacturing of AEMWE catalysts by exploring techniques for the fabrication of electrodes with a 3D structure. The unique morphology of 3D catalysts often results in higher catalytic activity, leading to faster reaction kinetics and facilitating better mass transport of reactants/products. This can contribute to improved durability, making them more resistant to degradation over time. Among the various 3D structures, carbon nanotubes (CNTs) stand out due to their exceptional electrical conductivity, high electrochemical stability, robust mechanical properties, and large specific surface area. Several synthesis methods for CNTs are available, notably chemical vapor deposition, and electrodeposition using a template with defined porosity to guide the growth of the nanostructures. The application of these strategies may lead to a cost-effective and efficient manner of producing high-performance catalysts for AEMWE.

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.

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.
