A fuel cell made of hydrogen, able to convert chemical energy into electrical energy.
A fuel cell made of hydrogen, able to convert chemical energy into electrical energy.

Hydrogen fuel cells are composed of two electrodes (a cathode and an anode), divided by an electrolyte membrane. Similar to electric batteries, the electricity is generated through a electrochemical reaction where chemical energy is converted into electric energy.

Popular processes to produce hydrogen fuel cells include the harnessing of natural gas, with carbon dioxide as the by-product, and through electrolysis. The first method is less environmentally friendly, yet the most popular in the industry so far. However, the second method is, not only, nearly carbon-neutral, but is also capable of producing water, through combining hydrogen with oxygen,

Current hydrogen fuel cells are less efficient than traditional electric batteries, but when mixed with air, hydrogen fuel cells display more favorable results, producing electricity roughly 40 per cent more efficiently than combustion engine technology.
