Noun(1) a negatively charged electrode that is the source of electrons entering an electrical device(2) the positively charged terminal of a voltaic cell or storage battery that supplies current
(1) An electron originating near the planar cathode and ultimately collected at electrode A will induce an equal charge at A and B during most of its journey.(2) The opening focuses the electrons emitted from the cathode onto the anode to a spot size preferably less than 40 nanometers.(3) Oxygen enters at the cathode , where it combines with electrons and is split into ions that travel through the electrolyte to react with fuel at the anode.(4) The trouble with the fuel cell is that it requires a barrier between the anode and the cathode because the oxidizing and reducing agents will corrode catalytic elements if allowed to intermix.(5) But because electrons must be supplied to the cathode by an external power source to drive this process, the cathode in an electrolytic cell has a negative charge.(6) Most fuel cells use a polymer electrolyte membrane to separate the cathode and anode.(7) Those same ions would then flow to the cathode , and after electrons were added, would end up as pure copper.(8) The electrons on the anode migrate via a wire to the cathode , the other electrode in the fuel cell, where they are electrochemically assisted to combine with the protons and produce hydrogen gas.(9) Therefore, in electrolytic cells, the cathode is the negative terminal and the anode is the positive terminal.(10) Researchers determined the optimum potential for switching the photocurrent to be - 0. 05V, where the anodic and cathodic photocurrents are about the same.(11) Welds made with these electrodes are cathodic to the base metal and thus resist galvanic corrosion.(12) The genetic interpretation of the relative mobility for the observed bands led us to assign an ├ö├ç├┐a├ö├ç├û to the most anodal allele, and a letter following the alphabetic sequence to each subsequent cathodal allele.(13) Interestingly, one sample had increased polyclonal, cathodal IgG, probably of the IgG, subclass; the AMCVs for this sample were relatively high (and higher than those for most IgG MC).(14) Two different regions of activity were identified for DIA, from which only the most cathodal was consistently interpreted.(15) There are three broad classes of corrosion-inhibiting admixtures, using different chemical mechanisms to control oxidation and the resulting corrosion - anodic inhibitors, cathodic inhibitors, and organic inhibitors.(16) The fact that identical electrons were emitted from cathodes of a range of materials under a range of conditions strongly suggested that the electron is a fundamental constituent of all atoms.
