(February 2021)Demonstration model of a direct methanol fuel cell (black layered cube) in its enclosure Scheme of a proton-conducting fuel cell A fuel cell is an electrochemical cell that converts the chemical energy of a fuel (often hydrogen)
The operation principle of the PEM fuel cell is that H 2 is supplied to the anode and O 2 to the cathode. This is achieved through gas flow channels, resulting in the generation of protons at the anode and current through an external circuit. Moreover, at the anode, H 2 is oxidised into protons and electrons.

Hydrogen production. To produce hydrogen, it must be separated from the other elements in the molecules where it occurs. Hydrogen can be produced from many different sources in different ways to use as a fuel. The two most common methods for producing hydrogen are steam-methane reforming and electrolysis (splitting water with
The worldwide demand for energy puts increasing pressure on the available carbon sources. The combustion of carbon-based fuels, e.g. natural gas and coal, cannot be sustained indefinitely, as carbon resources become depleted, unless effective technology is developed to recover and re-use the carbon dioxide combustion product. .
