What is a fuel cell based energy storage system?
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.
Can a fuel cell be used as an energy storage device?
When used as an energy storage device, the fuel cell is combined with a fuel generation device, commonly an electrolyzer, to create a Regenerative Fuel Cell (RFC) system, which can convert electrical energy to a storable fuel and then use this fuel in a fuel cell reaction to provide electricity when needed.
What are the benefits of fuel cells?
Fuel cells have several benefits over conventional combustion-based technologies currently used in many power plants and vehicles. Fuel cells can operate at higher efficiencies than combustion engines and can convert the chemical energy in the fuel directly to electrical energy with efficiencies capable of exceeding 60%.
What are fuel cells used for?
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.
Are fuel cells a high energy system?
To compare the power and energy capabilities, a representation known as the Ragone plot or diagram has been developed. A simplified Ragone plot (Figure 3) discloses that fuel cells can be considered to be high-energy systems, whereas supercapacitors are considered to be high-power systems.
Which fuel has higher storage of chemical energy than common battery materials?
In hydrogen and other hydrocarbon fuels has higher storage of chemical energy as compared with common battery materials (1). (Figure 1) shows the different reactions and processes that happens in various fuel cells (2). Fuel cells are electrochemical devices that convert chemical energy into electrical energy through a controlled redox reaction.
