New predictive structure-propertyfunction (SPF) and structure-propertyhazard (SPH) relationship models

Separation of the different layers of the assembly and recovering of the different materials or elements entering the composition of the different layers.

For electrode removing, cheap methods such as mechanical scratching will be firstly studied. The separation of electrode-electrolyte assembly will be also performed by grinding followed by thermal and chemical treatments. Numerous separation methods will be optimized and compared in order to limit chemical products use and energy consumption.

ASR on optimised compositions deriving from Ca2Fe2O5 and Ca3Co4O9 and promising composition evidenced by modelling

Composition deriving from the Ca2Fe2O5 and Ca3Co4O9 will be investigated in a first step. Depending on the modelling results (WP2), the study will be extended to the most promising lanthanum free composition. Partial substitution on the cation sites will be carried out to modulate the ionic transport properties of these materials. The conditions of synthesis will be optimised to decrease the grain size. Symmetrical cells will be prepared using screen printing. Pure materials and composites with the electrolyte (YSZ or GDC) will be studied as the impact of the electrode thickness on the performances. From this, ASR will be derived.

Embedding of Physic-based models in phenomenological models

Report on the embedding of Physic-based models in phenomenological models.

Toxicity tests

Results of human toxicity tests of new promising materials for SOEC compared to benchmark materials for exposure relevant endpoints.

Re-use of the recycled materials to prepare new materials for SOEC and prospecting for use in other applications

The first aim of the study is to obtain pure materials, which could be re-used for the preparation of new cells. Different separation and purification methods will be performed and compared. Nevertheless, in order to minimize the energy involved in the recycling process, the use of only partially purified compounds, and even of recycled mixtures materials, will be also considered.

Safe- and Sustainable by design approach developed based on proposed Integrated Testing Strategy (set up Virtual High Throughput Screening tools for design and virtual screening of novel compositions for electrolyte/electrode coatings

A communication kit will be made available to partners to manage the external communication to scientific and technologic audiences. It will include the project’s logo, website, templates for public presentations, project flyers, video-reports of research activities and results easily implementable in various web platforms.
