This service supports EIC Pathfinder, Transition and Accelerator Beneficiaries developing hydrogen technologies, fuel cells, electrolysers and battery systems. It enables targeted validation of materials, components and electrochemical devices accelerating prototype refinement, providing at the same time technical evidence for partnerships and investment discussions. The first phase of the service is a free initial consultation and feasibility assessment, during which CERIC experts analyse the Beneficiary’s technical challenges, evaluate the state of development and recommend the most relevant experimental approaches, creating an ad-hoc workflow to test and validated the Beneficiary materials and devices. The implementation phase combines advanced methods such as spectroscopy, diffraction, microscopy for the characterisation of materials, catalysts, membranes, electrodes and interfaces, as well as electrochemical testing of half-cells, single cells and cell stacks. Beneficiaries can access fuel-cell and electrolyser testing on efficiency, durability, degradation behaviour, and stress evaluation under controlled conditions.. At the end of the service, Beneficiaries receive a report summarising performance metrics, degradation pathways, limiting factors or optimisation steps according to the Beneficiary´s request. Certification-related constraints or safety considerations for energy storage materials and systems may also be addressed.
