Introduction
Water recovery in fuel cells refers to capturing water formed during the hydrogen-oxygen reaction to improve efficiency and manage humidity.

🧠 What It Means
In a PEM fuel cell: 2H₂ + O₂ → 2H₂O (plus electricity).
The water generated must be managed: recovered or drained.
Helps with internal cooling, humidification, and system reuse.
❗ Key Challenges
Balancing hydration — too much water = flooding; too little = drying out.
In cold climates, water recovery systems risk freezing.
Adds complexity to vehicle and stationary fuel cell systems.
🦁 Muzaffar’s Comment
“Fuel cells make water as they work — the smart ones know how to use it again.”
🦉 Sameer’s Comment
“The byproduct becomes a benefit — clever hydrogen engineering at play.”
