  1. galvanic cell is a electrochemical cell that derives electrical energy from chemical reactions taking place within the cell.In its simplest form, each half-cell consists of a metal and a solution of a salt of the metal.
    Electrolic cell An electrolytic cell has three component parts: an electrolyte and two electrodes (a cathode and an anode). The electrolyte is usually a solution of water or other solvents in which ions are dissolved

  2. galvanic cell is electric current is produced as a result of spontaneous redox reaction, and an electrolytic cell electric current is used to derive a non-spontaneous redox reaction.

  3. In electrochemistry, a galvanic cell- or voltaic cell- is an electrochemical cell used to convert chemical energy into electrical energy. The cell consits of a half-cell where either reduction or oxidation occurs. Galvanic cells are cells whose energy is produced by spontaneous reactions. The electrolytic cell is one used to cause a chemical change through the application of electrical energy. The cell uses electrical energy to make nonspontaneous redox reactions proceed.

  4. In contrast, galvanic cells are basically converting chemical energy into electrical energy by the use of spontaneous chemical reactions that take place at the electrode. It also use electrodes of different metals rather than electrolytic cell.

    For electrolytic cell, it is a type of nonspontaneous reaction that decomposes chemical compounds by electrical energy consisting of three components such as an electrocyte and two electrodes which are a cathode and anode. Also electrolytic cells use the same metals for cathode and anode rather than galvanic cells.

    They compare by that they both require the use of electrical energy. Also in comparison, the oxidation takes place at the anode and the electrons flow from the anode to the cathode.

  5. IN COMPARISON, GALVONIC AND ELECTROLYTIC CELL BOTH REQUIRE THE USE OF ELECTRICAL ENERGY. THE OXIDATION TAKES PLACE IN THE ANODE AND THE ELECRTONS FLOW FROM THE ANODE TO THE CATHODE. IN CONTRAST, THE GALVONIC CELLS CONVERT CHEMICAL ENERGY INTO ELCETRICAL BY THE USE OF SPONTANEUS CHEMICAL REACTIONS THAT WILL TAKE PLACE AT THE ELECTRODE. IN ELCTROLYTIC CELL, IT IS THYPE OF OF NONSPNTANEUS RECTION TAHT DECOMPOSES CHEMICAL COMPOUNDS BY ELECTRICAL ENERGY CONSISTING OF THREE COMPONENTS.
