H-LEAF

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.

BMQ is in charge of the following task in this project:

_ Investigation and characterization of nanoparticle inks of different compositions.

_ Research and development of the cathode and anode using the developed inks of electrocatalytic and porous metals.

_ Study of the scaling process and industrial production of electrocatalyst inks and GDL (Gas Diffusion Layers).
