Fueling a SOFC with agricultural waste derived biogas - Analysing the Swiss case -

Samuel Joseph Christian Majerus

The use of fuel cells for valorising agricultural and food-waste-derived biogas in Switzerland is studied. The Swiss agricultural case is characterised by farms with small numbers of animals (20 cows) and high feed-in tariffs for biogas derived electricity ...

Solar fuel processing efficiency for ceria redox cycling using alternative oxygen partial pressure reduction methods

Sophia Haussener, Meng Lin

Solar-driven non-stoichiometric thermochemical redox cycling of ceria for the conversion of solar energy into fuels shows promise in achieving high solar-to-fuel efficiency. This efficiency is significantly affected by the operating conditions, e.g. redox ...

Thermo-mechanical Reliability of SOFC Stacks During Combined Long-term Operation and Thermal Cycling

Jan Van Herle, Zacharie Wuillemin, Arata Nakajo, Fabio Greco

Thermo-mechanical issues in solid oxide fuel cells (SOFC) must be understood and overcome to meet the reliability standards for market implementation. This study presents a thermo-mechanical model of an SOFC-stack SRU. The analysis starts with the simulati ...
