WebA fuel, such as hydrogen, is fed to the anode, and air is fed to the cathode. In a hydrogen fuel cell, a catalyst at the anode separates hydrogen molecules into protons and electrons, which take different paths to the cathode. The electrons go through an external circuit, creating a flow of electricity. WebThe fuel cell produces power through a redox reaction between hydrogen and oxygen. At the anode, hydrogen is oxidized according to the reaction: producing water and releasing electrons. The electrons flow through an external circuit and return to the cathode, reducing oxygen in the reaction: producing hydroxide ions. the secret soldiers of benghazi true storyWebAug 12, 2024 · When the grain size is reduced, the hydrogen output characteristics begin to resemble behavior observed in silicon-containing aluminum.
