electrolyte diffusion
1Electrolyte — This article is about the ionic solution. For the R.E.M. song, see Electrolite. In chemistry, an electrolyte is any substance containing free ions that make the substance electrically conductive. The most typical electrolyte is an ionic solution …
2Polymer Electrolyte Membrane Fuel Cell — Die Polymerelektrolytbrennstoffzelle (engl. Polymer Electrolyte Fuel Cell, PEFC, auch Protonenaustauschmembran Brennstoffzelle, engl. Proton Exchange Membrane Fuel Cell, PEMFC oder Feststoffpolymer Brennstoffzelle, engl. Solid Polymer Fuel Cell,… …
3Overpotential — This article is about a concept in electrochemical use in electrical engineering. For overvoltage, see Overpotential (disambiguation). Overpotential is an electrochemical term which refers to the potential (voltage) difference between a half… …
4SUPERCONDUCTEURS IONIQUES — La matière peut prendre différents états (plasma, gaz, liquide, solide) qui se différencient par leur densité, leur capacité thermique massique et, en particulier, la valeur du coefficient de diffusion des espèces constituantes: atomes, ions,… …
5Glossary of fuel cell terms — The Glossary of fuel cell terms lists the definitions of many terms used within the fuel cell industry. The terms in this glossary may be used by fuel cell industry associations, in education material and fuel cell codes and standards to name but …
6ÉLECTROCHIMIE ET ÉLECTROLYSE — L’électrochimie décrit les relations mutuelles de la chimie et de l’électricité ou, mieux, des phénomènes couplés à des échanges d’énergie électrique. Ainsi, la presque totalité de la chimie, du fait de l’importance de la distribution et de la… …
7Membraneless Fuel Cells — convert stored chemical energy into electrical energy without the use of a conducting membrane as with other types of fuel cells. In Laminar Flow Fuel Cells (LFFC) this is achieved by exploiting the phenomenon of non mixing laminar flows where… …
8electrochemical reaction — ▪ chemistry Introduction any process either caused or accompanied by the passage of an electric current and involving in most cases the transfer of electrons between two substances one a solid and the other a liquid. Under ordinary… …
9Solid oxide fuel cell — A solid oxide fuel cell (SOFC) is an electrochemical conversion device that produces electricity directly from oxidizing a fuel. Fuel cells are characterized by their electrolyte material and, as the name implies, the SOFC has a solid oxide, or… …
10renal system — ▪ anatomy Introduction in humans (human body), organ system that includes the kidneys, where urine is produced, and the ureters, bladder, and urethra for the passage, storage, and voiding of urine. In many respects the human excretory, or… …
