The objective of the e-LEAF project is to develop, from a patented experimental proof of concept, fuel cells to be used in hydrogen-powered vehicles.

Using printed technologies, the project describes a novel fabrication methodology and Membrane Electrode Array (MEA) design flexible as a thin printed device with improved diffusion rate and reduced cost compared to conventional cell configuration.

Lower vehicle emissions since 2008 have already reduced the number of deaths attributable to air pollution by thousands and returned billions of euros in public health benefits. However, only little progress has been made in reducing its climate impact.

Among the various clean energy solutions, fuel cells are considered the most efficient solutions and are the basis of hydrogen-powered systems, aimed at meeting 24% of Europe’s energy needs by 2050.

Proton exchange membranes (PEMFC) position themselves as the most promising candidate for transport applications, key to achieving the EU’s energy sovereignty, decarbonisation and decentralisation objectives.

It is a manufacturing technology with low operating temperature, high power density, fast start-up capability and suitability for intermittent operation. It is capable of electrochemically converting the chemical energy of various fuels into electricity, by simply choosing catalysts in its MEA.

Eurecat is the coordinator of the e-LEAF project through its Functional Printing and Integrated Systems Unit, in charge of the development of a new technology for preparing components for fuel cells.
