Quick student answer

What should you know about (chemistry only) State that the overall reaction in a hydrogen fuel cell involves oxidation of hydrogen to produce water?

Direct answer

In Chemistry, this page helps you answer questions about (chemistry only) State that the overall reaction in a hydrogen fuel cell involves oxidation of hydrogen to produce water within Chemical cells and fuel cells (chemistry only). Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are Overall reaction and Oxidation of hydrogen.

Key terms

  • Overall reaction: The complete chemical change that occurs in a hydrogen fuel cell, where hydrogen gas is oxidised at the anode to produce water at the cathode.
  • Oxidation of hydrogen: The loss of electrons by hydrogen atoms in the fuel cell, forming protons that combine with oxygen to generate water.

Common trap

Confusion about oxidation: Remember that oxidation involves the loss of electrons, while reduction involves the gain of electrons. In the context of a hydrogen fuel cell, hydrogen is oxidized as it loses electrons to form water.
