Energy efficient hydrogen drying and purification for fuel cell vehicles

Hubert Girault, Heron Vrubel, Yorick Ligen

High-purity standards are required for hydrogen used in fuel cell vehicles. The relative abundance of contaminants is highly influenced by the production pathway. Hydrogen obtained from water electrolysis presents three main pollutants: Nitrogen, Oxygen an ...

Visualizing the importance of oxide-metal phase transitions in the production of synthesis gas over Ni catalysts

Stéphane François Jean Poitel

Synthesis gas, composed of H-2 and CO, is an important fuel which serves as feedstock for industrially relevant processes, such as methanol or ammonia synthesis. The efficiency of these reactions depends on the H-2 : CO ratio, which can be controlled by a ...

Development and verification of a methodology for neutron noise response to fuel assembly vibrations

Andreas Pautz, Hakim Ferroukhi, Abdelhamid Dokhane, Gaëtan Girardin, Dionysios Chionis

Nuclear reactors are stochastic systems, in which several parameters fluctuate even during steady-state conditions. In addition, structural components like fuel assemblies, vibrate due to strong hydraulic forces. This stochasticity is the cause of the neut ...

Ex-situ experimental benchmarking of solid oxide fuel cell metal interconnects

Jan Van Herle, Manuel Bianco

Solid oxide fuel cells (SOFCs) can convert hydrocarbon fuels, such as methane, into heat and electricity with a high conversion efficiency. The fuel flexibility of the SOFC derives from the high operating temperature (600-900 °C). Such a high temperature s ...
