Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. Who invented Fuel cell?1838 by Sir William Grove
2. What is the key development?Francis Thomas Bacon developed a significant hydrogen-oxygen fuel cell in 1932
3. What is the key principle?Electrochemical conversion of chemical energy to electricity via redox reactions
4. What is a fuel cell and how does it make electricity?A fuel cell is an electrochemical device that turns fuel and air into electricity. It has an anode, a cathode, and an electrolyte. The electrons travel through a circuit to create power.
5. Why are fuel cells better than batteries for long‑term power?Fuel cells keep working as long as they get fuel and air. Batteries run out because they store their reactants inside. Fuel cells can produce electricity for a long time.

Redox Reaction: A chemical reaction involving the transfer of electrons between species.
Electrolyte: A substance that conducts ions but not electrons, separating anode and cathode.
Cogeneration: The simultaneous generation of electricity and useful heat from a single fuel source.
