Fuel Cell

  • Fuel Cell: In this electrochemical cell, fuel loses electrons at one porous electrode while oxygen gains electrons at the alternate porous electrode.

  • The product of a fuel cell is water:
    2H2 +2H_2\ + O2 =\ O_2\ = 2H2O\ 2H_2O
  • Fuel cell reaction at anode:
    2H2 =2H_2\ = 4H+\ 4H+ +\ +4e−4e-
  • Fuel cell reaction at cathode:
    4H+4H+ +\ + O2 +\ O_2\ + 4e− =\ 4e-\ = 2H2O\ 2H_2O
  • The flow of the electrons, through the electric circuit, from the cathode to the anode generates a current. This cell is used to drive electric motors in the automotive industry.
