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.
PEMFC fuel cell systems that can operate at 95°C rather than 80°C would be significantly reduced in size facilitating their integration into heavy duty applications. However, this requires adapting their components to withstand these harsher operating conditions. Tasked with developing a Membrane Electrode Assembly (MEA), researchers at CEA-Liten have already reported promising results.
A new EU-funded project will support Europe’s energy transition by creating more resilient, decarbonised energy systems by advancing hydrogen electrolysers.
