  2. Anode - Wikipedia

    en.wikipedia.org/wiki/Anode

    The terms anode and cathode are not defined by the voltage polarity of electrodes, but are usually defined by the direction of current through the electrode. An anode usually is the electrode of a device through which conventional current (positive charge) flows into the device from an external circuit, while a cathode usually is the electrode through which conventional current flows out of ...

    en.wikipedia.org/wiki/Electrodialysis

    These cations also stay in the C stream, prevented from further migration toward the cathode by the positively charged anion-exchange membrane. [8] As a result of the anion and cation migration, electric current flows between the cathode and anode. Only an equal number of anion and cation charge equivalents are transferred from the D stream ...

  4. Cathode - Wikipedia

    en.wikipedia.org/wiki/Cathode

    The cathode supplies electrons to the positively charged cations which flow to it from the electrolyte (even if the cell is galvanic, i.e., when the cathode is positive and therefore would be expected to repel the positively charged cations; this is due to electrode potential relative to the electrolyte solution being different for the anode ...

    The lithium ions move around inside the positive side of the cell (cathode) and generate electrons that, being negatively charged, want to get to the negative side (anode) of the battery but can't ...

  6. Electrolysis - Wikipedia

    en.wikipedia.org/wiki/Electrolysis

    Oxidation of ions or neutral molecules occurs at the anode. For example, it is possible to oxidize ferrous ions to ferric ions at the anode: Fe 2+ (aq) → Fe 3+ (aq) + e −. Reduction of ions or neutral molecules occurs at the cathode. It is possible to reduce ferricyanide ions to ferrocyanide ions at the cathode: Fe(CN) 3-6 + e − → Fe(CN ...

  7. Ion - Wikipedia

    en.wikipedia.org/wiki/Ion

    From this fact it is apparent that most of the space of a crystal is occupied by the anion and that the cations fit into the spaces between them." [18] The terms anion and cation (for ions that respectively travel to the anode and cathode during electrolysis) were introduced by Michael Faraday in 1834 following his consultation with William ...

    This reaction can be driven in reverse by applying a voltage, resulting in the deposition of zinc metal at the anode and formation of copper ions at the cathode. [24] To provide a complete electric circuit, there must also be an ionic conduction path between the anode and cathode electrolytes in addition to the electron conduction path.

    en.wikipedia.org/wiki/Alkaline_anion-exchange...

    An alkaline anion-exchange membrane fuel cell (AAEMFC), also known as anion-exchange membrane fuel cells (AEMFCs), alkaline membrane fuel cells (AMFCs), hydroxide-exchange membrane fuel cells (HEMFCs), or solid alkaline fuel cells (SAFCs) is a type of alkaline fuel cell that uses an anion-exchange membrane to separate the anode and cathode compartments.
