Heterogeneous Catalytic Reactor for Hydrogen Production from Formic Acid and Its Use in Polymer Electrolyte Fuel Cells

Gabor Laurenczy, Nordahl Autissier, Katerina Stefania Sordakis, Martin Grasemann, Andrew Francis Dalebrook

A proof-of-concept prototype of a medium-scale heterogeneous catalytic reactor for continuous production of hydrogen through formic acid (FA) dehydrogenation has been developed. A commercial proton exchange membrane (PEM) fuel cell (FC) fed with the result ...

Modeling of Local Cell Degradation in Solid Oxide Fuel Cells: Cumulative Effect of Critical Operating Points

Daniel Favrat, Jan Van Herle, Stefan Diethelm, Antonin Faes, Zacharie Wuillemin, Arata Nakajo, Nordahl Autissier

A CFD model was developed to predict with accuracy the local electrochemical performance in an operating solid oxide fuel cell. A particular focus was given on the study of performance limitations and degradation sources caused by the design of the fuel ce ...

Investigation of Local Electrochemical Performance and Local Degradation in an Operating Solid Oxide Fuel Cell

Daniel Favrat, Jan Van Herle, Stefan Diethelm, Zacharie Wuillemin, Arata Nakajo, Andres Müller, Nordahl Autissier

In order to characterize a new SOFC stack design, to investigate degradation processes and to validate models, a diagnostic test station was designed and realized. It allows to characterize repeat-elements locally by measuring the local potential, current ...

Impact of Materials and Design on Solid Oxide Fuel Cell Stack Operation

Jan Van Herle, Stefan Diethelm, Zacharie Wuillemin, Arata Nakajo, Nordahl Autissier

Planar SOFC stack technology based on a unique concept (SOFConnex™) uses structured gas distribution layers between unprofiled metal sheet interconnects and thin Ni-YSZ anode supported electrolyte cells. The layers are flexible both in material and designa ...

A methodology for thermo-economic modeling and optimization of solid oxide fuel cell systems

François Maréchal, Daniel Favrat, Nordahl Autissier, Francesca Palazzi

In the context of stationary power generation, fuel cell-based systems are being foreseen as a valuable alternative to thermodynamic cycle-based power plants, especially in small scale applications. As the technology is not yet established, many aspects of ...

Design of 500 W Class SOFC Stack with Homogeneous Cell Performance

Jan Van Herle, Stefan Diethelm, Zacharie Wuillemin, Arata Nakajo, Nordahl Autissier, Emily Thorn

Our planar SOFC stacking technology uses unprofiled metallic interconnects (MIC) and thin cells of tape cast anode supported YSZ. The key element is the gas diffusion layer (GDL) between cell and MIC, which consists of so-called SOFConnex™. Using square ce ...
