Already involved in the Program & Priority Research Equipment – Decarbonized Hydrogen (PEPR-H2) through the EquipPEX+ DurabilitHy and the PEMFC95 project, our teams have, this year again, successfully responded to the latest call for projects 2021: 4 projects submitted, 4 projects selected by the ANR!
♦ DAEMONHyC | Durable Anion Exchange Membrane electrOlyzer for largescale greeN HYdrogen produCtion
The electrochemical performance and stability of alkaline membranes and ionomers have been greatly improved in recent years, paving the way for anion exchange membrane water electrolyzers (AEMWE). These systems combine the cost advantages of conventional alkaline electrolysis with those of proton exchange membrane water electrolysers. Through a multidisciplinary consortium, we will develop stable and high performance membranes, ionomers and precious metal-free catalysts. In situ and operando characterization methods associated with a multi-scale model will allow us to obtain relevant information at all scales from the catalytic site to the elementary cell. The technological valorization of the results (rise in TRL), will be fast thanks to the involvement of two French industrialists whose ambitions in the production of decarbonated hydrogen are notable.

♦ MATHyLDE | Materials for hydrogen production to Lower our dependency on existing ones
Proton Exchange Membrane Water Electrolysis (PEMWE) offers the advantage of being able to be efficiently coupled with renewable energy generation and produce ultra-pure hydrogen, pressurized and without a purification step. Materials are at the heart of these devices:
iridium loading represents 6% of the cost of these devices and must be lowered,
the membranes must have high ionic conductivities and, ideally, integrate means of recombination of dihydrogen and dioxygen and
porous transport layers must minimize constriction resistances while facilitating the transport of two-phase mixtures.
The durability of the materials must also be improved and for this purpose, we will use advanced in situ characterization methods. Finally, a modeling of the material transport and heat, electrons and ions transfers will allow to optimize the material shaping and the operating conditions of the PEMWEs systems developed in the framework of the project.

♦ HYSyPEM | Optimization of HYbrid energy SyStem with multi-stack PEM fuel cells for heavy duty transportation applications
The HYSySPEM project aims at improving hybrid PEM fuel cell systems for heavy duty mobility applications (truck, marine, train, airplane) with a systemic approach. The optimization of electrical and fluidic architectures in a modular multi-stack approach will be performed at several scales (fuel cell system and hybrid system) and on key components (compressor, power converter topologies at voltage levels from 800V to 1500V). Local control improvements and power and energy management at the hybridization level will be coupled with a fault tolerant control approach at the power converter and hybridization level to ensure a very high level of reliability.
In this project, LEMTA is mainly involved in two workpackages:
The first one is related to the study of the self-wetting of a PEM fuel cell cell fed with dry gas. Indeed, the simplification of the system and in particular the suppression of the air humidifier is a possible way to improve the durability while lowering the cost.
The second one concerns the electrical architecture and the research of power converter topologies allowing an optimal management of the system. The objective will be to develop the technological building blocks related to the use of hybrid multistack systems for heavy transport applications.
3 theses in cotutelle with FEMTO-ST and CEA will be initiated in this project

♦ BHyoLOHC | Biobased Polyols as a High Capacity Hydrogen Carrier Organic Liquid
Hydrogen can be stored or transported in the form of organic liquids called LOHC (Liquid Organic Hydrogen Carrier). The objective of the project is to develop new catalytic materials for hydrogenation and electro-dehydrogenation of biosourced polyols (ethylene glycol and glycerol), and to evaluate their reaction properties and stability. LEMTA will mainly participate in the study of the electrocatalytic hydrogen production step and will aim at characterizing globally and locally the reaction using a segmented cell allowing to measure the performances and to detect the limitations associated with the material transfer. Optimization methods will be proposed.
