overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Electrochemical cells are devices that convert chemical energy into electrical energy through electrochemical reactions. They consist of two electrodes—an anode and a cathode—immersed in an electrolyte, enabling the flow of electrons to generate electric current. Common examples include batteries and fuel cells, which are widely used in portable electronics, transportation, and stationary power storage.
