In recent years, the key principles of electric power industry have radically changed and number studies on development devices for electrical energy storage in a different form such as mechanical or chemical has rapidly increased. This review gives brief description these devices. The attention is focused redox flow batteries (RFBs), promising type capable efficiently operating distributed grids, order to eliminate imbalance between time-varying electricity production by ‘unconventional...
Although microbial fuel cells (MFC) could be a promising energy source, their implementation is largely limited by low performance. There are several approaches to overcome this issue. For example, MFC performance can enhanced using redox mediators (RM) capable of transferring electrons between microorganisms and electrodes. The other, quite novel approach use zero-gap electrochemical cells, which minimize the distance electrodes and, therefore, its internal resistance. This work aims...
Abstract A concept of high energy density (ED) hydrogen–bromate flow battery was supported by experiments with cells 0.1 to 50 cm 2 apparent areas. H /NaBrO 3 gas diffusion anode, proton exchange membrane (PEM), and carbonaceous flow‐by or flow‐through cathodes were employed. Estimates show that the theoretical ED /bromate (HBFB) exceeds /O fuel (FC) in air‐deficient environments. At cathode HBFB, aqueous, concentrated bromate (non‐toxic, stable) is reduced bromide a six‐electron process....

Keeping mind non-electroactivity ion possibility to ensure its rapid transformation via a redox-mediator cycle (EC′ mechanism) is analyzed. Alternative route bromine/bromide redox couple comproportionation reaction inside phase considered within framework several...
Abstract A great deal of research has been dedicated to improving the performance vanadium redox flow battery (VRFB). In this work, we propose design a cell for testing membrane electrode assembly VRFB, which enables optimization field, conditions charge‐discharge tests, and nature components (electrodes, membrane) with minimal time material expenses. The essence proposed is that system channels distributing electrolyte made by cutting shaped holes in sheets graphite foil (GF). This manner...
We study the drift of a Brownian particle in periodically tapered tube, induced by longitudinal time-periodic force amplitude |F| that alternates sign every half-period. The focus is on velocity dependence period, which usually considered not tractable analytically. For large we derive an analytical solution gives as function and period well geometric parameters tube. shows how decreases from its maximum value to zero infinity (adiabatic regime) zero. Our results are excellent agreement with...
Abstract Theoretical analysis has been developed for the reduction process of non‐electroactive bromate anion through an autocatalytic cycle composed reversible Br 2 ‐to‐Br − transformation and irreversible (owing to high acidity solution) comproportionation reaction. Owing character this redox‐mediating (EC′′ mechanism) even a tracer amount in bulk solution may result enormous values current, which are determined by diffusion‐limited flux either anions or protons. The latter case analyzed...

Diffusion in a tube of periodically varying diameter occurs slower than that cylindrical because diffusing particles get trapped wells the periodic entropy potential which is due to variation cross-section area. To quantify slowdown one has establish relation between effective diffusion coefficient particle and geometry, very complicated problem. Here we show how overcome difficulties case expanded conical tube, where find an approximate solution for as function parameters determining geometry.
