★ Must-know
📌 Fuel cells require a continuous source of fuel and oxygen or air, whereas batteries generate electromotive force from chemicals already present inside the battery.
Further detail
Fuel cells need continuous fuel and oxygen, whereas batteries consume chemicals stored inside them.
1. What distinguishes a fuel cell from a battery in the way reactants are used?
2. A device must operate while hydrogen and air are supplied from external sources; which characteristic identifies it as a fuel cell rather than a battery?
3. How does a fuel cell generate electricity while keeping ion and electron transport separate?
What does a fuel cell convert into electricity?
Chemical energy of a fuel.
What ions react with oxygen in a fuel cell?
Positively charged hydrogen ions.
What do fuel cells require continuously to operate?
A continuous source of fuel and oxygen or air.
How do fuel cells differ from batteries in fuel supply?
Fuel cells need continuous fuel and oxygen; batteries use internal chemicals.
What components does a fuel cell use to separate ion and electron transport?
An anode, an electrolyte, and a cathode.
What is the function of the electrolyte in a fuel cell?
It allows ions to pass but prevents electrons from passing.
