PREMHYOME

PRE-INDUSTRIALIZATION OF COMPOSITES HYBRID MEMBRANES FOR PEMFC

Project-ADEME-TITEC 2014 | 1494C0030

July 2014 – June 2017

The PREMHYOME project targeted the development of hybrid PEMFC membranes designed mainly for stationary application with low hydration level and operating temperature above 80°C. The objective of the project was to demonstrate the technical and economic potential of the innovative solution developed in the project by favoring industrially viable approaches. This research project is part of the development, optimization and integration of new nanocomposite hybrid membranes exhibiting proton conductivity in Membrane Electrode Assemblies (MEA).

From a technical point of view, the main objectives of the EXALAME project were (i) to optimize the synthesis of hybrid nanoparticles for operation in air in a temperature range of 90-100 °C, (ii) to scale up the synthesis of hybrid nanoparticles up to 1Kg and (iii) to implement large surface MEA by automated methods.

During the PREMHYOME project, SPECIFIC POLYMERS’ research efforts were geared towards the synthesis of poly(sodium 4-styrenesulfonate) grafted silica particles (Si-PSSNa) dispersed in PVDF-HFP polymer matrix. Si-PSSNa particles were synthesized the grafting of an alcoxysilane functional ATRP precursor on the surface of silica particles. It was then possible to build up a well-defined polymeric coating. It was demonstrated that the grafting density of PSSNa chains, as well as their molecular weight, can be tuned to adjust the protonic membrane properties. SPECIFIC POLYMERS fully developed the Si-PSSNa synthesis at laboratory scale and is now producing them at 200 grams scale. Research work was also achieved to improve the synthesis pathways by reducing the copper content during ATRP polymerization or by using non-toxic solvents.
