Workpackage 1: Project management
D.1.2 – Project shared workspace implemented and operational - CONFIDENTIAL

To fulfil two fundamental internal project communication requirements: i) efficient exchange between partners of information about GAIA project ii) decentralised and secured archiving of the documents generated, one independent and secured web-based communication tool: Project Shared Workplace – PSW has been implemented with a restricted access for project partners only. Among all the functionalities installed on this PSW, for now partners have a total access to the following tools:

    • Document sharing and archiving
    • Meeting organization
    • General project communication
    • Online working document

The PSW maintenance is therefore an on-going activity that will go along with the project lifetime

   Workpackage 2: Requirements, Test Methods and Operating Conditions, Benchmarking, Cost assessment
D.2.1 – Fuel cell operation conditions, performance and durability requirements - CONFIDENTIAL

For the use of Membrane-Electrode-Assemblies in future automotive fuel cell systems, the definition of the operating conditions for an efficient and fast development process is crucial. Therefore, Deliverable D2.1 in a very detailed form
describes the operating conditions based on virtual fuel cell systems for FCEV. The focus lies on the transfer of fuel cell system operating conditions to available state-of-the-art test rigs located at the individual project partners to obtain fuel cell system relevant results.

D.2.2 – Decision on bipolar plate hardware and recommendation on small scale test cell Hardware to be used - CONFIDENTIAL

The requirements and testing protocols defined in Deliverable D2.1 and in Deliverable D2.3 have to be verified by in situ testing in appropriate cell hardware by systematic test cycles. For this reason, publically available information from other EU FCH JU funded projects (Autostack-Core, INSPIRE, VOLUMETRIQ) was collected and rated according to the needs of GAIA, described in D2.1. Based on this information the decision for automotive stack hardware setup was made with the project partners ZSW and JMFC. Cell hardware for 50 cm² cell testing, especially the flow field design, was shared with JMFC, TUM and CNRS.

   Workpackage 4: Catalyst Support and Catalyst Design
D4.1 - Characterisation method for ionomer-support interaction strength developed - PDF

In catalyst inks for PEM fuel cell applications, the interaction carbon support starts at the ink making step and can influence final catalyst layer, including ionic conductivity and mass improve understanding of the way carbon supports and typical interact, this deliverable report summarises attempts to technique capable of quantifying the strength of the interaction.
CNRS have validated ITC as being a straightforward method to of the ionomer-carbon interaction. The method is sufficiently discriminate between carbon samples with different degrees of by nitrogen and increasing the nitrogen content of the carbon heat of adsorption of Nafion® on the modified carbon.
At JMFC, changes in the zeta potential for a range of of how the solvent type and concentration govern the charge the ionomer and carbon support. It was clear that in aqueous dispersions of Nafion®, Vulcan XC72R had a weaker interaction with the ionomer than Ketjen EC300J, due to a lower (less positive) zeta potential.
For a straightforward quantification of ionomer-carbon interaction strength, the centrifuge method of measuring the amount of free ionomer was very successful and here it was shown that in mixed aqueous-alcohol dispersions, Vulcan XC72R had a stronger interaction with the ionomer than Ketjen EC300J, in agreement with the zeta potential results for the carbons in the same dispersant, but in contrast to the situation in a purely aqueous system.
Fluorine-NMR was found to be less straightforward as a way to measure carbonionomer interaction strength in work at TUM. Despite reports in the literature, this work demonstrated that the signal-to-noise ratio was not sufficient to quantify the interaction at the low ionomer concentrations needed.
`In summary, four different techniques were explored, with three of them showing successful quantification of ionomer-support interactions, and the fourth still holding promise of a successful outcome. The early identification and implementation of these techniques within the GAIA project means that WP4 is in a strong position to deliver modified supports that will enable catalyst layers to be designed with the right properties to meet the challenging 1.8 W/cm2 target in the project.

   Workpackage 7: Communication, Dissemination & Maximising Impact
D.7.1– Project Website - PDF

The GAIA project website is designed to fulfil project communication and dissemination needs for the benefit of the scientific community and the public through relevant information including:

    • project overall objectives, partner & work package information
    • project activities: news, meetings
    • project progress: scientific publications, conference presentations, public domain reports
    • project resources: links, related events …
    • project contact information

All the partners will collectively participate in the dissemination objective of the website by providing up-to-date information

D.7.2– Dissemination protocol and knowledge management - CONFIDENTIAL

This report presents the dissemination protocol for the GAIA project, the procedure for “Open Access” to peer reviewed research articles, internal rules, information on support from the EU members and the strategy for Knowledge Management within the project.
