The appropriate assessment of mechanical properties is essential to design ceramic matrix composites. The size effect of strength plays a key role for the material understanding and the transfer from lab-scale samples to components. In order to investigate the size effect for carbon fiber-reinforced silicon carbon (C/C-SiC) under tensile load, a te...

The penetration of fuel cells and electrolyzers in energy systems calls for their scale-up to the gigawatt (GW) level. High temperature solid oxide cells (SOC) offer unrivaled efficiencies in both electrolysis and fuel cell operation. However, they are made of ceramics and are brittle by nature. Consequently, a high mechanical strength to avoid fai...

High temperature solid oxide fuel cell (SOFC) is regarded as a unique electrochemical device to convert the chemical energy of a large diversity of fuels into electricity and heat with high efficiency and low emission. The electrolyte-supported cell (ESC) design is proven to be one of the most feasible SOFC technologies for commercial applications....

In this work, dense gadolinium-doped ceria (GDC) thin-films with thickness of 0.15 and 0.5 µm were fabricated on 90 µm thick 3YSZ electrolytes by electron beam physical vapor deposition (EB-PVD), and integrated into electrolyte supported solid oxide cells (ESC) as Sr-barrier layer. Operated at 860°C, the ESC with 0.5 µm GDC thin-film outperformed t...
