Progress on anode supported cell stacks (SOFCONNEX design, 50 m2 per cell) is presented. A 6-cell stack and a 8 cell-stack were mounted and tested with hydrogen fuel at 800 degre C, yielding 100 W el and 140 W el, corresponding to a power density of 1kW el ...
In this project we develop hydrogen sensors based on nanoscaled discontinuities (nanogaps) in palladium (Pb). These nanogaps reversibly close and open upon hydrogen/air cycling due to an increased lattice constant in the hydrated state. Therewith, an elect ...
Hydrogen prodn. using earth abundant metals is one of the important challenges facing an energy economy based upon solar fuels. Schemes that incorporate the photo-oxidn. of water must also include schemes for efficiently converting released protons and ele ...
Correctly controlling a fuel cell system and maintaining correct operating conditions, particularly under dynamic load variations, is difficult without advanced, multivariable control systems. In order to design and implement such controllers, an appropria ...
Ni-YSZ anode supports show a fundamentally different microstructure from screenprinted Ni-YSZ anodes on YSZ electrolyte supports. Of high density and composed of fine zirconia and nickel oxide to allow for cofiring with a thin zirconia electrolyte film (5 ...
The use of ammonia as a source of hydrogen for fuel cells has received little attention until now. Ammonia offers several advantages over hydrogen as a fuel and is produced commercially in massive quantities and as a biogas. This paper describes the result ...
In the framework of the EU-project SOLZINC, a 300-kW solar chemical pilot plant for the production of zinc by carbothermic reduction of ZnO was experimentally demonstrated in a beam-down solar tower concentrating facility of Cassegrain optical configuratio ...
Maintaining a fuel cell (FC) system in correct operating conditions when subjected to fast load changes requires good system control. The best results are typically achieved using model-based control strategies. This paper elaborates a control-oriented pro ...
Cross-correlated relaxation of multiple-quantum coherences in NMR was used to investigate hydrogen bonds in Watson-Crick base pairs, based on the interference between various relaxation mechanisms. [on SciFinder (R)] ...
To increase power density at reduced temperature operation of SOFC, thin film 8YSZ electrolytes were deposited on Ni-YSZ anode support plates by tape casting and cofiring. Cathode behaviour, limiting cell output at lower temperature, was studied in more de ...
