Dr. Hab.
After studying fluid mechanics for various applications at ALSTOM and CNES, Joël PAUCHET joined the CEA in 2001 where he specialized in PEMFC from 2004. Joël played a key role in understanding coupled transfers in the core of PEMFC: adaptation of the Comsol software to simulate performance, development of the "pore network modeling" approach to study two-phase transfers in porous media, development of local characterization methods during operation...
Joël has coordinated several projects at the European level with various industrials and research organizations, supervised numerous PhD students, and is the author of several patents and scientific publications in international peer-reviewed journals.
Joël is always looking to increase performance and durability of PEMFC, notably by improving the 3D structure of its porous components.

PEMFCs: - Transfers in porous media (diffusion layers, active layers); - Mechanisms limiting performance; - Water management (modeling, instrumentation); - Development of two-phase modeling using the Pore Network Modeling (PNM) method; - Coupling modeling and experimentation; - Inter-scale coupling; - Two-phase cooling.
Over the last decade or so, CEA-Liten has been developing composite coatings intended for various applications, including thermal protection, fire barriers, and resistance to erosion and chemical corrosion. ACHIEF (Innovative high performance Alloys and Coatings for HIghly EFficient intensive energy processes, 2020 – 2024, grant 958374), an EU project coordinated by CEA, has demonstrated the benefits of these materials in industrial applications of resistance to acid corrosion.
The pioneering MultiPLHY project demonstrating renewable hydrogen production has reached a key milestone: The consortium partners have successfully started up the world's largest multi-megawatt high-temperature electrolyzer (HTE) in an industrial environment at Neste's renewable products refinery in Rotterdam, the Netherlands.
