What is electrochemical hydrogen storage?
Historically, electrochemical hydrogen storage was the basis of commercially popular metal hydride (MH) batteries, where the purpose was storing energy rather than hydrogen as a fuel. In any case, understanding the electrochemical hydrogen storage is of vital importance for the future of energy storage whether electrochemically or by hydrogen fuel.
How do fuel cells work?
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.
What are the different types of electrochemical systems for hydrogen storage?
Various types of electrochemical systems for hydrogen storage are reviewed. It is described that hydrogen storage can be the basis of energy storage via supercapacitors and batteries. Electrochemical hydrogen storage is also part of energy conversation via fuel cells.
