What are electrochemical energy storage systems?Electrochemical energy storage systems have the potential to make a major contribution to the implementation of sustainable energy. This chapter describes the basic principles of electrochemical energy storage and discusses three important types of system: rechargeable batteries, fuel cells and flow batteries.
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 three types of electrochemical energy storage?This chapter describes the basic principles of electrochemical energy storage and discusses three important types of system: rechargeable batteries, fuel cells and flow batteries. A rechargeable battery consists of one or more electrochemical cells in series.
What is a fuel cell?A fuel cell is an electrochemical cell in which the reactants supplying the energy are not stored in the cell itself but rather are continuously supplied to the electrodes from an external source.
What is an example of a fuel cell?A common example is a hydrogen–oxygen fuel cell: in that case, the hydrogen and oxygen can be generated by electrolysing water and so the combination of the fuel cell and electrolyser is effectively a storage system for electrochemical energy. Both high- and low-temperature fuel cells are described and several examples are discussed in each case.
How do electrochemical energy storage devices work?The principle of operation of electrochemical energy storage devices is based on the formation of a chemical reaction between the electrolyte and the electrodes contained in it. Then there is a shortage of electrons on one of the electrodes and an excess on the other. This allows chemical energy to be converted into electrical ener
