Hydrogen Fuel Cell: Features, Working and Applications21 June 2021
A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. The basic principle is the reverse reaction of electrolyzed water. Hydrogen and oxygen are supplied to the anode and the cathode respectively. After the hydrogen diffuses out through the anode and reacts with the electrolyte, electrons are released to the cathode through an external load.
What is Surge?09 February 2022
