Fuel Cell Basics | Department of Energy

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 the cathode. In a polymer electrolyte membrane fuel cell, a catalyst separates hydrogen atoms into protons and electrons, which take ...

Hydrogen bond

A symmetric hydrogen bond is a special type of hydrogen bond in which the proton is spaced exactly halfway between two identical atoms. The strength of the bond to each of those atoms is equal. It is an example of a three-center four-electron bond. This type of bond is much stronger than a "normal" hydrogen bond.

Hydrogen explained: Clean is Green, Blue is Dirty

If no climate pollutants – carbon dioxide, methane or other hydrocarbons – are released in the process, then the hydrogen product can be described as clean. Right now, clean hydrogen is green hydrogen. If it creates climate pollution, the hydrogen is not clean. And that means all blue, grey, brown and black hydrogen is dirty. Matt Agius.

Hydrogen explained

Hydrogen is an energy carrier. Energy carriers transport energy in a usable form from one place to another. Elemental hydrogen is an energy carrier that must be produced from another substance. Hydrogen can be produced—or separated—from a variety of sources, including water, fossil fuels, or biomass and used as a source of energy or fuel.
