📖 1. Fuel cell definition

🔑 Key Concepts & Definitions

• Fuel cell: A device that converts chemical energy directly into electrical energy through an electrochemical reaction.
• Chemical energy: The energy stored in chemical bonds, released during reactions.
• Electrical energy: The energy resulting from electric charges in motion.
• Electrochemical reaction: A reaction involving the transfer of electrons between substances, occurring at electrodes.

📝 Essential Points

• A fuel cell converts chemical energy directly into electrical energy.
• The conversion occurs through an electrochemical reaction, not combustion.
• Fuel cells produce electricity continuously as long as fuel is supplied.

💡 Key Takeaway

Fuel cells are devices that transform chemical energy directly into electrical energy via electrochemical processes, operating continuously with a fuel supply.

📖 2. Key electrochemical reaction

🔑 Key Concepts & Definitions

• Anode: Electrode where hydrogen splits into protons and electrons.
• Cathode: Electrode where oxygen reacts to form water.
• Protons: Hydrogen ions produced at the anode.
• Electrons: Charge carriers that flow through an external circuit, generating electricity.
