Renewable energy and Energy efficiency
Fuel cells are widely accepted as one of the best potential solutions to extend the range of battery-powered electric vehicles. CEA Tech institute Liten has been conducting low-temperature PEMFC (proton exchange membrane fuel cell) R&D for years; these fuel cells are designed for both transportation and stationary applications.
Liten is active across the entire fuel-cell value chain (with the exception of the membrane), working to improve electrode materials, come up with more effective ways of assembling fuel-cell components, enhancing catalysts, and integrating smart capabilities into fuel-cell systems. The objectives of this research are multiple: improve system lifespans; reduce the amount of platinum (a rare, expensive metal) required; and achieve competitive total cost of ownership to ensure that fuel cells become an economically-viable alternative to current solutions.
ALL TECHNOLOGY PLATFORMS
Researchers at Liten, a CEA Tech institute, set out to determine whether or not micro cogeneration affects fuel-cell aging. The first long-duration tests conducted under the Propice project provided some answers.
The Nanocharacterization platform’s two Titan transmission electron microscopes recently received some major upgrades. They now provide more than just images, delivering detailed information on the chemistry of the materials being analyzed.
Liten, a CEA Tech institute, and Safran recently developed a new low-mass, high-energy-density hybrid energy source that can operate within a wide temperature range. The R&D was commissioned by the French Directorate General for Armaments.
Liten, a CEA Tech institute, recently produced the first-ever cylindrical lithium-sulfur battery. The prototype’s performance indicates a bright future for the batteries!
Improved management of water in proton exchange membrane fuel cells (PEMFCs) could help reduce costs and lengthen lifetimes, both of which are crucial to the fuel cells’ commercial success. Research conducted at Liten, a CEA Tech institute, in conjunction with CNRS/IMFT* and PSI** has unlocked some of the secrets to further progress.
How to collaborate with CEA Tech teams ?
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
