fuel-cell

A fuel cell is an electrochemical device that converts the chemical energy of a fuel, such as hydrogen or methane, into electrical energy through a process called electrolysis. It consists of two electrodes, an anode and a cathode, separated by an electrolyte. When fuel is supplied to the anode, it is oxidized to produce electrons and positively charged ions. The electrons flow through an external circuit, producing electrical power, while the positively charged ions migrate through the electrolyte to the cathode, where they combine with oxygen to produce water and heat. Fuel cells are highly efficient and produce zero emissions, making them an attractive alternative to conventional power sources. They have a variety of applications, including power generation for buildings and vehicles, and portable power for electronic devices.
