EXALAME

POLYFUNCTIONAL CATALYTIC COMPLEXES FOR MEMBRANE ELECTRODE ASSEMBLY WITHOUT NAFION® FOR PEMFC TYPE BATTERIES

Project-ADEME-TITEC 2012 | 294C0091

November 2012 – February 2016

The EXALAME project targeted the manufacture of optimized, reliable and reproducible membrane-electrode assemblies, from innovative materials (membranes, catalysts and electrodes) for fuel cell application. Complete demonstration systems were targeted leading to the manufacture of membrane electrodes assembly (MEA) using innovative components and technologies capable of industrialization.

The innovative components were optimized and selected for their compatibility with industrial specifications both in terms of operation (performance and durability) and manufacture cost. The EXALAME project represented an opportunity to reduce the gap towards ambitious requirements for the deployment of fuel cell systems (MEA targeted performances: loading rate 0.2-0.5 mg/cm², power density 1W/cm², voltage drop <1µV/h, surfaces 100-400 cm², cost <10 €/cm² of active surface).

During the project, SPECIFIC POLYMERS participated in the industrial development of polymeric materials for the MEA. In particular, we targeted the synthesis of sodium poly(styrene sulfonate) (PSSNa) polymers containing disulphide moieties able to act as anchoring groups for the synthesis of platinum grafted-PSSNa catalytic layers. During the project, SPECIFIC POLYMERS was able to custom design the PSSNa polymer architecture and to achieve various polymerization degrees (DPn). It was shown that increasing the PSSNa chain length brought about a decrease in the number of anchors on the surfaces of the nanoparticles that finally led to an increase of the platinum-based nanoparticles catalytic activity.
