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 electrolyser 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.
