Modelling of the Wastewater Treatment Process Using Microbial Bioelectrochemical Technologies

The wastewater is potential processing facilities, from which you can receive bioenergy and biochemicals. Wastewater treatment using microbial fuel cells (MFC) is one of the strategies of biological treatment of industrial and agricultural wastewater. The purpose of this work is modeling of process of wastewater treatment by means of mediator microbic fuel elements and also assessment of efficiency of microorganisms Escherichia coli used as the biocatalyst in the course of bioelectrochemical oxidation of various substrates (glucose, sucrose and citric acid) in neutral environments.

Electrooxidation of Formic Acid at Nanostructural Composites of Palladium and Polyaniline


A kinetics of formic acid anodic oxidation at electrodes consisting from composites of palladium with polyaniline is studied. It was found that the contact of palladium with polyaniline does not result in the electrocatalytic activity enhancement, that differs such composites from composites of palladium with polyelectrolytes.

УДК 541.135


The wastewater is potential processing facilities, from which you can receive bioenergy and biochemicals. Recovery of energy and valuable products can partially compensate for the cost of wastewater treatment and reduce some of the dependence on fossil fuels

Solid oxide fuel cells with film electrolyte: problems and perspectives

УДК 539.23 + 544.6.018


This paper reviews the methods used nowadays for solid-oxide electrolyte film deposition. Problems and perspectives in the field of development of solid oxide fuel cells with film electrolyte are discussed.

Nanostructure сatalysts, сomposed of сomposites of platinum, ruthenium, polyelectrolytes and nanotubes

УДК 541.138


Electrocatalysts for methanol oxidation was studied. They were prepared on the base of carbon nanotubes, covered by polyelectrolytes with differently charged functional groups, which was changed by platinum with subsequent reduction. Then ruthenium was spontaneous deposited on metal platinum. The prepared catalysts were more active compared to commertial ETEK Pt-Ru (50:50 at. %) catalysts.

Cycle life of alkaline matrix fuel cell stack

DOI: 10.18500/1608-4039-2015-15-4-175-179

The reasons, that lead to the performance loss of alkaline matrix electrochemical generator (ECG) based on hydrox cell and therefore reduce the fuel cell stack cycle life, are highlighted in this article. It is shown that storage of ECG, preserved with a special gas mixture within up to 20 years, doesn't lead to noticeable characteristic fluctuation.

Icomparative studying of kinetics of bioelectrochemical oxidation of glucose in neutral environments by means of the microorganisms Escherichia coli and Enterobacter cloacae

The method of the rotating disk electrode studied electrochemical behavior redox mediator methylene blue in bioelectrochemical system «glucose – cell – mediator – electrode» and is shown that methylene blue is reversible oxidation-reduction a mediator and can be applicable at realization of the microbic media even anode on the basis of glucose and cell of Escherichia coli and Enterobacter cloacae.

Metallization of electrolitic die of alkaline matrix fuel cell

В работе рассмотрена металлизация электролитной матрицы щелочного матричного топливного элемента, обусловленная растворением платинового катализатора на кислородном электроде этого элемента. Показано, что уровень металлизации зависит от условий функционирования топливного элемента и структурных особенностей его составляющих.
