It is generally believed that the Nernst—Planck equation provides a sound basis for the analysis of mass transport phenomena in electrochemistry. However, the Nernst—Planck equation cannot account for "inertial effects" caused by one or more constituents changing velocity with position or time. By...

An accurate mathematical description of the charge transfer rate at electrodes due to an electrochemical reaction is an indispensable component of any electrochemical model. In the current work we use the generalized Frumkin-Butler-Volmer (gFBV) equation to describe electrochemical reactions, an equation...
Mass transport in reverse electrodialysis for sustainable energy generation At the electrodes a redox couple is used to mitigate the transfer of electrons. The ion exchange membranes are one of the key elements in the RED process as they, together with ion transport phenomena and concentration polari...

The study of magnetic field effects in electrochemistry can provide new insights into fundamental principles that can lead to the development of new tools and techniques for controlling (electro-)chemical reactions5,6. In particular, the study of the influence of magnetic fields on electrochemical rea...
Z Siroma,K Yasuda - 《Electrochemistry》 被引量: 2发表: 2012年 Energy flow and thermal voltage analysis of water-cooled PEMFC stack under normal operating conditions To improve the utilization of electric energy and heat energy of the fuel cell stack, it is necessary to explore the composition...
Mass transfer coefficients kL are small, however. For the smaller bubble dispersions, mass transport is controlled by diffusion rather than by convection. 展开 关键词: Experimental/ adsorption bubbles chemical reactions convection desorption diffusion electrolytes interface phenomena mass transfer two-phase ...
In this study we use a rotating disc electrode to emulate a practical bioelectrochemical system, while decoupling mass transport from shear stress. This is the first study to isolate the metabolic and structural changes in electroactive biofilms due to shear stress. We find that increased shear ...
aThe water chemistry and electrochemistry inside the crack crevice or at the crack tip could be significantly different from the bulk water chemistry due to the limitation of the mass transport rate within the crack enclave and the resultant segregation of impurity ions and the depletion of oxygen ...
