Development of rechargeable monopolar and bipolar zinc/air batteries

Christos Comninellis, Christian Schlatter

For the development of a rechargeable zinc/air battery, La0.6Ca0.4CoO3-catalyzed (perovskite) bifunctional oxygen electrodes and pasted zinc electrodes were prepd. and tested in monopolar zinc/air cells. In addn., a bipolar Zn/air stack was tested using re ...

Use of Zr/ZrO2 as a counter electrode for the minimization of loss reactions in single-compartment electrolysis cells

Christos Comninellis

The use of ZrO2 membrane on counter electrodes (e.g. Zr) is proposed for controlling the mass transfer rates to the electrode and therefore the extent of possible loss reactions. A comparative study was undertaken to examine the influence of the prepn. tec ...

The industrial electrolytic regeneration of Mn2(SO4)3 for the oxidation of substituted toluene to the corresponding benzaldehyde

Christos Comninellis

A new industrial process for the electrolytic regeneration Mn2(SO4)3 is presented in which: a slurry of MnSO4/Mn2(SO4)3 in 55% H2SO4 was used as a carrier, the electrolyte is purified with an optimum mode before electrogeneration, and a new industrial elec ...

Charge separation and charge transport in nanostructured TiO2 film electrodes

Ulf Anders Hagfeldt

Photoelectrochem. measurements have been performed on film electrodes consisting of linked nano-sized TiO2 colloids. The film thickness ranged from 1-40 μm. The film network was attached to a thin transparent conducting layer of SnO2 allowing for photogene ...

Nanostructured TiO2 semiconductor electrodes modified with surface attached viologens: applications for displays and smart windows

Michael Graetzel, Ulf Anders Hagfeldt

Viologen derivs. adsorbed on TiO2 surfaces in nanocryst.-nanoporous electrodes have been studied with respect to electrochromic phenomena. The transparent nature and the high internal surface area of these electrodes are very beneficial for this purpose. T ...

Cyclic Cleavage of Water into H2and O2by Visible Light with Coupled Redox Catalysts

Kuppuswamy Kalyanasundaram

A complete system for cleavage of water by light (250‐W lamp) comprises the catalysts Pt and RuO2 and the sensitizer Ru(bpy) as well as the acceptor methylviologen (MV2+). 150 ml of solution gave 0.6 ml of H2 and 0.3 ml of O2 in h. ...

An ADMM-based Coordination and Control Strategy for PV and Storage to Dispatch Stochastic Prosumers: Theory and Experimental Validation

Mario Paolone, Colin Neil Jones, Fabrizio Sossan, Rahul Kumar Gupta, Emil Namor, Enrica Scolari, Luca Fabietti

This paper describes a two-layer control and coordination framework for distributed energy resources. The lower layer is a real-time model predictive control (MPC) executed at 10 s resolution to achieve fine tuning of a given energy set point. The upper la ...

Sulfur Poisoning Recovery on a Solid Oxide Fuel Cell Anode Material through Reversible Segregation of Nickel

Jan Van Herle, Davide Ferri, Oliver Kröcher, Hossein Madi, Andre Heel

The perovskite-type mixed oxide La0.3Sr0.55Ti0.95Ni0.05O3−δ (LSTN) is demonstrated to exhibit the remarkable property of structural regeneration, where Ni can be reversibly exsoluted from the host perovskite lattice resulting in a regenerable Ni catalyst f ...
