Hydrogen energy storage primarily relies on a process called electrolysis. During electrolysis, an electric current is passed through water (H2O), causing it to split into hydrogen (H) and oxygen (O) gases (2H2O ⇾ 2H2 + O2). The hydrogen gas can then be stored in tanks or underground caverns for later use. When needed.

Fuel Cell. Fuel cells are cells that directly transform the chemical energy of a fuel cell into electrical energy. Fuels such as hydrogen (H 2), carbon dioxide (CO 2), methane (CH 4), propane (C 3 H 8), methanol (CH 3 OH), and others are used to create electrical energy in the cells shown below. The fuel cell is constantly supplied with fuel, while the products are
Proton Exchange Membrane Fuel Cell Working. The PROTON EXCHANGE MEMBRANE FUEL CELL (PEMFC) is also called a polymer electrolyte membrane fuel cell. A polymer is composed of molecules with a high molecular weight that can be formed by the addition of many smaller molecules. The PEMFC uses hydrogen fuel and oxygen (obtained from the air) as an
