Hydrogen Fuel Cell Basics

What is the type of reaction that takes place in a hydrogen fuel cell?

• Electrochemical reaction

• Nuclear reaction

• Chemical reaction

• Thermal reaction

Answer explanation

A hydrogen fuel cell operates through an electrochemical reaction, where hydrogen and oxygen react to produce electricity, water, and heat. This distinguishes it from nuclear, chemical, or thermal reactions.

Which component is essential for the electrochemical reaction in a hydrogen fuel cell?

• Anode

• Cathode

• Membrane

• All of the above

Answer explanation

In a hydrogen fuel cell, the anode, cathode, and membrane all play crucial roles in the electrochemical reaction.
