The temperature profile generated by a thermo-electro-chemical model was used to calculate the thermal stress distribution in a tubular solid oxide fuel cell (SOFC). The solid heat balances were calculated separately for each layer of the MEA (membrane ele ...
Oxygen diffusion is treated in a dense electronically conducting cobaltate pellet blocked ionically on one surface, electronically on the other, and sealed on its cylindrical periphery. A procedure is developed for extracting the chemical diffusion and sur ...
In this thesis, the electrochemical promotion of lr and Rh based catalysts was studied for the complete combustion of ethylene and propylene. The study was performed by using two types of electrocatalytical cells: a classical, pellet type cell and a tubula ...
A wide range of applications in neurotechnological research rely on planar microelectrode arrays (MEA) but the disadvantage of these systems is the low density of electrodes caused by the problem of wiring a great number of electrodes. In turn this results ...
The new dye complex bis[4,4'-di(2-(3-methoxyphenyl)ethenyl)-2,2'-bipyridine][4,4'-dicarboxy-2,2'-bipyridine]ruthenium(II) dihexafluorophosphate (1) was prepd., characterized by absorption spectroscopy and adsorbed onto nanocryst. TiO2 electrodes. The resul ...
Electrochem. promotion (EP) of gas-phase catalysis with O2--conducting solid electrolytes is addressed. The behavior of the ref. electrode, prepd. by deposition of a gold film, was found to be quasi-reversible, 12O2/O2- being the potential detg. redox coup ...
A review with refs. concerning electrochem. promotion of catalysis is presented. Recent progress made in our lab. in the field of electrochem. promotion of heterogeneous catalytic gas reactions is presented. The phenomenon consists of non-Faradaic modifica ...
A review is given on the so-called electrochem. promotion (EP) denoting an elec. controlled modification of the activity and/or selectivity of a heterogeneous catalyst. Efficient EP in dispersed catalyst systems can be achieved using porous solid-electroly ...
A thin aqueous layer is formed between the polymeric ion-selective membrane and an inner gold electrode. Its composition can be altered upon sample changes, which leads to drifting potentials. It is shown by theory and experiment that interfering ions ente ...
Thin films consisting of nanorods of hematite (α-Fe2O3) with controlled orientation onto transparent conductive glass substrates have been tested as photoelectrochem. cells. These films allow a more efficient transport and collection of photogenerated elec ...
