Electrochemical oxidation of ammonia (NH4+/NH3) on thermally and electrochemically prepared IrO2 electrodes

Nico de Rooij, Christos Comninellis, Olivier Frey, Agnieszka Kapalka, Stéphane Fierro, Kai Udert

The electrochemical oxidation of ammonia (NH4+/NH3) in sodium perchlorate was investigated on IrO2 electrodes prepared by two techniques: the thermal decomposition of H2IrCl6 precursor and the anodic oxidation of metallic iridium. The electrochemical behav ...

Nanoporous YSZ film in electrolyte membrane of Micro-Solid Oxide Fuel Cell

Paul Muralt, Silviu Cosmin Sandu, Yan Yan, Samuel Rey-Mermet

Yttria stabilized zirconia (YSZ) with 8 mol% Y was deposited by reactive magnetron sputtering onto oxidized (100) silicon substrates. It was possible to switch film texture from (111) to (200) by applying a strong RF substrate bias. Transmission electron m ...

Ageing of anode-supported solid oxide fuel cell stacks including thermal cycling, and expansion behaviour of MgO-NiO anodes

Jan Van Herle, Stefan Diethelm

This paper reports on medium term tests of anode-supported five-cell short stacks, as well as on some separate anode development. Two stacks were operated under steady-state conditions: one with unprotected metal interconnects, H-2 fuel and 0.35 A cm(-2) ( ...

Compact 100 W stacks using thin components of anode supported cells and metal interconnects

Jan Van Herle, Raphaël Ihringer, Nicolas Badel, Nordahl Autissier, Diego Larrain, Joseph Sfeir

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 ...

Degradation of asymmetrical Pt/SRO/PLZT/Pt capacitors: Role of Pt and oxide electrodes

Nava Setter, Alexander Tagantsev, Igor Stolichnov

Role of Pt and SRO electrodes in polarization fatigue of PLZT film ferroelectric capacitors is studied. We show that asymmetrical Pt/SRO/PLZT/Pt structure exhibits unusual dependence of the endurance of switching polarization on the driving ac electric fie ...
