Introduction. A fuel cell is a device that uses hydrogen (or hydrogen-rich fuel) and oxygen to create electricity. Fuel cells are more energy efficient than combustion engines and the hydrogen used to power them can come from a variety of sources. If pure hydrogen is used as a fuel, fuel cells emit only heat and water, eliminating concerns
A hydrogen fuel cell is an electrolyzer in reverse where hydrogen and oxygen are combined to produce electrical energy. The basic operations of a fuel cell are shown in Fig. 24.1. At the anode, the hydrogen gas ionizes and releases electrons. Because the electrolyte is ionically conducting and electrically insulating, the hydrogen
Electrolysis is a leading hydrogen production pathway to achieve the Hydrogen Energy Earthshot goal of reducing the cost of clean hydrogen by 80% to $1 per 1 kilogram in 1 decade ("1 1 1"). Hydrogen produced via electrolysis can result in zero greenhouse gas emissions, depending on the source of the electricity used.
