Answer:

a) In a fuel cell, electrical energy is produced by the reaction of hydrogen with oxygen.

Explanation:

  • A fuel cell is an electrochemical device that turns chemical energy into electrical energy.
  • The oxygen is reduced at the cathode and the hydrogen is oxidized at the anode in a hydrogen-oxygen fuel cell.
  • When you combine these two reactions, you get hydrogen combustion, which produces a lot of heat.
  • Direct hydrogen combustion is uncontrollable, although it can be regulated to some extent using an electrochemical cell.
