🧠 What It Means
Lightweight, efficient, and clean.
Used in hydrogen cars, buses, forklifts, and backup power.
Operates at low temperature for quick startup.
❗ Key Challenges
High cost due to platinum catalyst.
Sensitive to temperature, humidity, and contaminants.
Needs pure hydrogen to run efficiently.
