Strontium Migration at the GDC-YSZ Interface of Solid Oxide Cells in SOFC and SOEC Modes

Jan Van Herle, Marco Cantoni, Emad Oveisi, Arata Nakajo, Pierre Burdet, Giorgio Rinaldi

Strontium migration from the oxygen electrode to the interface between the electrolyte and interlayer was investigated in solid oxide cells in fuel cell (SOFC) and electrolysis (SOEC) modes. Four samples were imaged by focused ion beam scanning electron mi ...

Evaluation of Protective Coatings for SOFC Interconnects

Jan Van Herle, Michele Bianco

Chromium poisoning is a widely recognized degradation process in solid oxide fuel cells (SOFC). Stainless steel interconnect plates, in direct contact with the cathode, have been identified as the major chromium source, raising a need for electrically cond ...

Fabrication of structured anode-supported solid oxide fuel cell by powder injection molding

Jan Van Herle, Antonin Faes, Zacharie Wuillemin, Amédée Zryd

Powder Injection Molding (PIM) gives the possibility to produce, at an industrial rate, ceramic parts with fine details. It is thus a possible approach to reduce the fabrication costs of Solid Oxide Fuel Cells (SOFCs). This work presents fabrication and el ...

Material Study of Micromachined Thin Film Solid Oxide Fuel Cells

Yan Yan

Miniaturized, low temperature Solid Oxide Fuel Cells (SOFCs) that operate below 600 °C are promising for supplying electrical power to portable devices. Thin electrolyte membranes of less than one micrometer thickness have been shown to yield reasonable po ...

Chromium Poisoning

Josef Andreas Schuler

This thesis focuses on Cr-poisoning in solid oxide fuel cells (SOFC), which currently presents a key challenge for the development of this technology. By the implementation of dedicated experimental tools, this work offers a new access to, and comprehensio ...
