  2. Electrolytic cell - Wikipedia

    en.wikipedia.org/wiki/Electrolytic_cell

    An electrolytic cell is an electrochemical cell that utilizes an external source of electrical energy to force a chemical reaction that would otherwise not occur. [ 1 ] : 64, 89 [ 2 ] : GL7 The external energy source is a voltage applied between the cell's two electrodes ; an anode (positively charged electrode) and a cathode (negatively ...

    en.wikipedia.org/wiki/Anion_exchange_membrane...

    Oxygen gas can enter the hydrogen half-cell and react on the cathode side to form water, which reduces the efficiency of the cell. Gas cross-over from the H 2 to the O 2 evolution side can pose a safety hazard because it can create an explosive gas mixture with >4%mol H 2 .

    en.wikipedia.org/wiki/Electrolyte

    Electrolytic conductors are used in electronic devices where the chemical reaction at a metal-electrolyte interface yields useful effects. In batteries , two materials with different electron affinities are used as electrodes; electrons flow from one electrode to the other outside of the battery, while inside the battery the circuit is closed ...

  5. Anion-exchange membrane - Wikipedia

    en.wikipedia.org/wiki/Anion-exchange_membrane

    Anion exchange membranes are used in electrolytic cells and fuel cells to separate reactants present around the two electrodes while transporting the anions essential for the cell operation. An important example is the hydroxide anion exchange membrane used to separate the electrodes of a direct methanol fuel cell (DMFC) [ 1 ] or direct-ethanol ...

  6. Electrochemical cell - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_cell

    An electrolytic cell is an electrochemical cell in which applied electrical energy drives a non-spontaneous redox reaction. [5] A modern electrolytic cell consisting of two half reactions, two electrodes, a salt bridge, voltmeter, and a battery. They are often used to decompose chemical compounds, in a process called electrolysis.

    en.wikipedia.org/wiki/Proton_exchange_membrane...

    The performance of electrolysis cells, like fuel cells, is typically compared through polarization curves, which are obtained by plotting cell voltages against current densities. The primary sources of increased voltage in a PEM electrolyzer (the same also applies for PEM fuel cells ) can be categorized into three main areas, Ohmic losses ...
