High temperature electrolysis system and method
Demetri Psaltis, Pooria Hadikhani
The present invention concerns an electrolysis system for high temperature electrolysis including a plurality of flow-based electrolysis units configured to receive an electrolyte solution and to perform electrolysis to provide a first output gas and a sec ...
2023Long-term evolution of solid oxide fuel and electrolysis cell 3-D microstructure
Solid oxide fuel cells (SOFC) are highly efficient electrochemical conversion devices for the production of electricity that combine fuel flexibility with low emissions of pollutants. The reverse operation in electrolysis mode (SOEC) allows storing electri ...
EPFL2019Hydrogen reduction of molybdenum oxide at room temperature
The color changes in chemo-and photochromic MoO3 used in sensors and in organic photovoltaic (OPV) cells can be traced back to intercalated hydrogen atoms stemming either from gaseous hydrogen dissociated at catalytic surfaces or from photocatalytically sp ...
Springer Nature2017Electrochemical Model of a Triode Solid Oxide Fuel Cell
Jan Van Herle, Stefan Diethelm, Arata Nakajo, Priscilla Caliandro
A Triode Solid Oxide Fuel Cell is a novel cell architecture that consists of two circuits: an auxiliary circuit, operated in electrolysis mode, and a conventional main fuel cell circuit. During triode operation, performance enhancement can be expected espe ...
2015Steam and Co-Electrolysis Sensitivity Analysis on Ni-YSZ Supported Cells
Jan Van Herle, Stefan Diethelm, Giorgio Rinaldi
The present paper investigates the variation in performances in steam electrolysis and co-electrolysis of steam/CO2 on SOEC single cells.In electrolysis mode, a sensitivity analysis was performed looking in particular at the effects of temperature (750°C a ...
2015Electrolysis and Co-Electrolysis Performance of SOE Short Stacks
Jan Van Herle, Stefan Diethelm
In this study, two short SOE stacks (6-cells) were characterized in steam-electrolysis mode. The first was based on Ni-YSZ supported cells with LSCF-based air electrodes. The second included LSC-based air electrodes specifically developed within the SOFC60 ...
Wiley-V C H Verlag Gmbh2013Experimental investigation of unstrained diffusion flames and their instabilities
In this thesis, thermal-diffusive instabilities are studied experimentally in diffusion flames. The novel species injector of a recently developed research burner, consisting of an array of hypodermic needles, which allows to produce quasi one-dimensional ...
