Introduction
An oxidant in a hydrogen fuel cell is the substance (usually oxygen or air) that reacts with hydrogen to generate electricity.

🧠 What It Means
Accepts electrons in the electrochemical reaction.
In PEMFCs, the oxidant is typically ambient air.
Enables the reaction that forms water and electricity.
❗ Key Challenges
Oxygen purity affects efficiency.
Air contaminants (e.g. CO, NOx) can poison the catalyst.
Balance between airflow, power output, and water management.
🦁 Muzaffar’s Comment
“No oxidant, no spark — it’s half the fuel cell reaction, but 100% critical.”
🦉 Sameer’s Comment
“Oxygen may be free, but how you use it decides how efficient your hydrogen system is.”
