In fuel cells, electrical energy is generated from chemical energy stored in the fuel.
Fuel cells can be used in a wide range of applications, providing power for applications across multiple sectors, including transportation, industrial/commercial/residential buildings, and long-term energy storage for the grid in reversible systems.
Fuel cells are electrochemical devices that convert chemical energy into electrical energy through a controlled redox reaction. They are distinct from batteries in that they require a continuous supply of fuel and oxidant (usually oxygen) to operate, while batteries store their energy internally.
A fuel cell-based energy storage system allows separation of power conversion and energy storage functions enabling each function to be individually optimized for performance, cost or other installation factors. This ability to separately optimize each element of an energy storage system can provide significant benefits for many applications.
Fuel cells have attracted attention as they are eco-friendly energy generators that convert chemical energy to electrical energy electrochemically . Like batteries, fuel cells use electrodes and electrolytes but produce continuous electricity via an external fuel supply rather than storing energy .
