Write a balanced half-cell equation for the reaction occurring at the anode. ignore phases in the reaction.
r-ruslan [8.4K]

The balanced half-cell equation for the reaction occurring at the anode is  H2 ---> 2H(+) + 2e(-)

E<u>xplanation:</u>

  • The balanced half-cell equation taking place at the anode is explained below
  • The product produced in the reaction in the fuel cell is water.
  • H2 ---> 2H(+) + 2e(-)
  • In the above reaction, the oxidation state of hydrogen switches from 0 to +1.
  • It is becoming oxidized by delivering two electrons at the anode.
  • In the fuel cell, hydrogen molecules get oxidized to hydronium ions.Thus half-reaction is the oxidation reaction.
