Question

Write a balanced half-cell equation for the reaction occurring at the anode. ignore phases in the reaction.

Answer 1

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

Explanation:

• 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.
