the point where or path by which a voltaic current enters an electrolyte or the like
the electrode of an electrolyte cell at which oxidation occurs; electrons flow away from the anode in the external circuit; it is usually at the electrode that corrosion occurs and metal ions enter solution
A positive (+) electrode The point where electrons exit from a device to the external electric circuit
Positive electrode made of carbon in electrolytic cells used in the smelting process
The positive end of an electric field Also the electrode in an electrochemical cell toward which the anions flow and the electrode where oxidation occurs
The negative electrode The electrode at which an oxidation reaction (loss of electrons) occurs
One of two electrodes in a fuel cell or battery The anode, the negative post of the fuel cell, conducts the electrons that are freed from the hydrogen molecules so that they can be used in an external circuit It has channels etched into it that disperse the hydrogen gas equally over the surface of the catalyst
A rectangular plate of metal cast in a shape suitable for refining by the electrolytic process
The positive end of an electric field Used to describe the electrode in an electrochemical cell toward which anions flow and the electrode at which oxidation occurs
electrode at which electrons are released during corrosion The half reaction at the anode is called oxidation and the metal is said to be oxidized The anode is the electrode that disintegrates during corrosion
The positive terminal of an electrolytic cell or battery In EDM, incorrectly applied to the tool or electrode
In an electrochemical cell, the electrode at which oxidation occurs; the positive electrode in an electrolytic cell and the negative electrode in a voltaic cell
the positive electrode toward which negative particles (anions, electrons) move within a device such as the cells of a battery, electrolytic cells and diodes [return to top]
The electrode where oxidation occurs in an electrochemical cell It is the positive electrode in an electrolytic cell, while it is the negative electrode in a galvanic cell The current on the anode is considered a positive current according to international convention; however, in electroanalytical chemistry the anodic current is often considered negative Contrast with cathode
An electrical element in laser excitation which attracts electrons from a cathode An anode can be cooled directly by water or by radiation
the negatively charged terminal of a voltaic cell or storage battery that supplies current
The positive pole of an electric battery, or more strictly the electrode by which the current enters the electrolyte on its way to the other pole; opposed to cathode
a positively charged electrode by which electrons leave an electrical device the negatively charged terminal of a voltaic cell or storage battery that supplies current
In electronics, an anode is the positive electrode in a cell such as a battery. Compare cathode. the part of a battery that collects electrons, often a wire or piece of metal with the sign (+) cathode (anodos , from ana- + hodos ). Terminal or electrode from which electrons leave a system. In a battery or other source of direct current, the anode is the negative terminal. In a passive load it is the positive terminal. In an electron tube, electrons from the cathode travel across the tube toward the anode; in an electroplating cell, negative ions are deposited at the anode
When two metals are connected in an electrolyte, they will form a galvanic cell, with the higher metal in the galvanic series being the anode The anodic will oxidize and produce an electrical current which protects the cathode from corrosion

An anode attached to a metal object, such as a boat or underground tank, to inhibit the object's corrosion. The anode is electrolytically decomposed while the object remains free of damage
