Fuel cells

Fuel cell is a kind of power generation device that directly converts chemical energy in fuels and oxidants into electricity (with no Carnot cycle and high energy conversion). The birth and development of fuel cells are based on multiple disciplines of electrochemistry, electrocatalysis, electrode process kinetics, material science, and chemical process. Both the anode and cathode of fuel cells need to contain a certain amount of electrocatalyst to accelerate the electrochemical reaction on the electrodes. In this chapter, the basic structure, energy storage mechanism, electrode material (especially the oxygen reduction reaction electrocatalyst), and application prospects of fuel cells are briefly reviewed.
