A fuel cell converts chemical energy into

heat

heat is ur answer

The fuel cell follows a chemical reaction to change over hydrogen-rich fuel into electricity.

Explanation:

An fuel cell is made out of an anode, a cathode, and an electrolyte film. It works by going hydrogen through the anode of a power device and oxygen through the cathode. At the anode site, the hydrogen particles are part into electrons and protons.

The protons go through the electrolyte film, while the electrons are constrained through a circuit, producing an electric flow and abundance heat. At the cathode, the protons, electrons, and oxygen consolidate to create water particles.
