Characterisation of powder and pellets

Summary of deliverable D3.2. In this deliverable the characterisations of powder and pellets produced for the HyCARE system and performed by the partners are discussed. GKN produced at the industrial scale up to 200 kg as a first batch for the prototype tank and afterwards up to 4 tons for the final demonstration tank the powder material of the selected composition. The produced material that includes 2% of binder (Lot IX-20015, 200 kg) has been distributed among the partners in form of powder and pellets for its characterization and the development of a first prototype module of the integrated system. Furthermore, the large 4 t production has been characterized at GKN (Lot 570119000/1-4, 4 tons) and related results are also presented. In details: structure, microstructure, particle size, density, thermal conductivity, heat capacity, composition, hydrogen storage properties (reversible capacity, thermodynamics, kinetics), poisoning and cycling properties have been reported.
