overpotential
21Amperometric titration — refers to a class of titrations in which the equivalence point is determined through measurement of the electric current produced by the titration reaction. It is a form of quantitative analysis.BackgroundConsider a solution containing the… …
22Overvoltage — This article is about a concept in electrical engineering. For use in electrochemistry, see overpotential. Voltage spike. When the voltage in a circuit or part of it is raised above its upper design limit, this is known as overvoltage. The… …
23Formic acid fuel cell — Direct formic acid fuel cells or DFAFCs are a subcategory of proton exchange membrane fuel cells where, the fuel, formic acid, is not reformed, but fed directly to the fuel cell. Their applications include small, portable electronics such as… …
24Platinum black — (Pt black) is a fine powder of platinum with good catalytic properties. The name of platinum black is due to its black color. Platinum black is widely used as a thin film covering solid platinum metal, forming platinum electrodes for applications …
25Luggin capillary — A Luggin capillary (also Luggin probe, Luggin tip, or Luggin Haber capillary) is a small tube that is used in electrochemistry. The capillary defines a clear sensing point for the reference electrode near the working electrode. [ cite… …
26Faraday efficiency — Faradic Efficiency (also called coulombic efficiency or current efficiency ) describes the efficacy with which current (electrons) are transfered in a system facilitating an electrochemical reaction. The word faraday in this term refers to the… …
27Electrochemical reaction mechanism — In chemistry, an electrochemical reaction mechanism is the step by step sequence of elementary steps, involving at least one outer sphere electron transfer, by which an overall chemical change occurs [Bard, A.J. L.R. Faulkner, Electrochemical… …
28Bulk electrolysis — is also known as potentiostatic coulometry or controlled potential coulometry . [Bard, A.J.; Faulkner, L.R. Electrochemical Methods: Fundamentals and Applications. New York: John Wiley Sons, 2nd Edition, 2000.] [Skoog, D.A.; West, D.M.; Holler, F …
