where does reduction take place in an electrochemical cell?
at the anode
salt bridge





























a salt bridge, in electrochemistry, is a laboratory device used to connect the oxidation and reduction half-cells of a galvanic cell (voltaic cell), a type of electrochemical cell. it maintains electrical neutrality within the internal circuit, preventing the cell from rapidly running its reaction to equilibrium. if no salt bridge were present, the solution in one half cell would accumulate negative charge and the solution in the other half cell would accumulate positive charge as the reaction proceeded, quickly preventing further reaction, and hence production of electricity.

metal–air electrochemical cell





























a metal–air electrochemical cell is an electrochemical cell that uses an anode made from pure metal and an external cathode of ambient air, typically with an aqueous or aprotic electrolyte. during discharging of a metal–air electrochemical cell, a reduction reaction occurs in the ambient air cathode while the metal anode is oxidized. the specific capacity and energy density of metal–air electrochemical cells is higher than that of lithium-ion batteries, making them a prime candidate for use in electric vehicles. however, complications associated with the metal anodes, catalysts, and electrolytes have hindered development and implementation of metal–air batteries.
