New technology for the generation of green hydrogen.
The H-LEAF project develops a PEM (Proton Exchange Membrane) electrolyser based on a new national patented technology.
H-LEAF focuses on the research of new scalable and sustainable components, coatings, materials and processes to overcome current limitations in the provision of materials for hydrogen production, vital to the energy transition in Spain.
The project promotes scientific research to obtain new electrode and membrane designs using scalable industrial printing techniques free of perfluorinated chemicals.
H-LEAF develops new bipolar plates using technologies such as stamped stainless steel substrate and 3D printing with recycled titanium powder, as well as corrosion resistant advanced coatings. These plates will replace the current ones, reducing costs and allowing mass manufacturing.
Additionally, the project addresses hydrogen compression using a novel piston system with advanced materials.
The final result will be an advanced demonstrator, reflecting the know-how of the consortium and reaching a TRL 6, with an electrolyser with a power of up to 1 kW validated on a test bench. This demonstrator will allow the evaluation of the final characteristics of the new system and components developed.
Eurecat participates in the H-LEAF project through four Units:
- The Functional Printing and Integrated Systems Unit acts as coordinator and develops the membrane electrode assemblies (MEA) and stack, formulates H-LEAF dyes for electrocatalysts and membranes; and validates the MEA and the electrocatalyst up to 1kW.
- The Chemical Technology Unit develops a new membrane free of perfluoroalkyl substances (PFAS).
- The Metallic and Ceramic Materials Unit develops new corrosion resistant coatings for bipolar plates obtained by 3D printing of recycled titanium powder.
- The Waste, Energy and Environmental Impact (WEEI) Unit performs the lifecycle analysis of the components and fabrication methodology of H-LEAF.
The multidisciplinary H-LEAF consortium is made up of companies and technology centres.
