Electrode reactions are fundamental processes in electrochemistry where oxidation and reduction occur at the interface between an electrode and an electrolyte. These reactions are crucial for the operation of batteries, fuel cells, and electrolysis systems, as they facilitate the transfer of electrons and the conversion of chemical energy into electrical energy or vice versa.

Electrochemistry is the branch of chemistry that studies the relationship between electricity and chemical reactions, focusing on the movement of electrons in redox reactions. It plays a crucial role in various applications, including batteries, fuel cells, corrosion prevention, and electroplating.

Oxidation and reduction are chemical processes that involve the transfer of electrons between substances, fundamentally altering their chemical properties. Oxidation refers to the loss of electrons, while reduction refers to the gain of electrons, and these processes always occur simultaneously in a reaction known as a redox reaction.

Fuel cells are devices that convert chemical energy from a fuel into electricity through an electrochemical reaction, typically using hydrogen as the primary fuel. They offer a clean and efficient alternative to combustion-based energy sources, with applications ranging from portable electronics to large-scale power generation and transportation.
