3 FCH Test Center

4 DTU Energy Technologies for energy conversion and storage 250 employees mainly at Risø Campus, Denmark More than 100 working on fuel cells and electrolysis Fuel cells R&D and testing since 1987 Since 2010 commercial testing through FCH Test Center Copenhagen DTU Risø Campus Roskilde

5 DTU Energy Focus on industrial collaboration and industrial processes Fundamental investigations component manufacture SOFC, SOEC, HT-PEM, H 2 storage, batteries and more Materials and component development Manufacturing processes for ceramics Advanced testing Characterization Modelling

6 FCH Test Center Testing Training Consultancy Advanced testing and demonstration of components and systems. Standardized test procedures

7 Testing

8 Electrochemical testing - SOFC/SOEC iv-curves and impedance spectroscopy Finger print combines testing at a number of temperatures with several gas compositions Reveal the performance of individual parts of the cell Performed at beginning and end of test, it will explain degradation mechanisms Cells, small stacks, full size stacks Open source software:
