Fuel cells

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.

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.

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.

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.

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.

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.
