Fuel Cells

Why Study Fuel CellsHow Fuel Cells WorkResearch and Development GoalsTechnical TargetsFuel cells work like batteries, but they do not run down or need recharging. They produce electricity and heat as long as fuel is supplied. A fuel cell consists of two electrodes—a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around an electrolyte. A fuel, such as hydrogen, is fed to the anode, and air is fed to th...See more on energy.govRoyal Society of Chemistry

Technical FAQs 4

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 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 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.

Can regenerative fuel cells provide energy storage?

Electrochemical systems, including flow batteries and regenerative fuel cells, offer promising solutions to this challenge, possessing the capability to provide large-scale, long-duration energy storage, thereby complementing the rapid response of batteries and the high energy density of fuels [5, 6].
