Hydrogen is usually produced by electrolysis and can be stored in underground caverns, tanks, and gas pipelines. Hydrogen can be stored in the form of pressurized gas, liquefied hydrogen in cryogenic tanks,
Read MoreHydrogen is the most abundant element in our universe, making up about 75% of its total mass. On Earth, naturally occurring hydrogen gas is found in very small quantities. Instead, most hydrogen atoms are bound to other atoms – for example, water is a molecule containing hydrogen and oxygen atoms. Since it takes energy to separate hydrogen
Read MoreThey produce electricity and heat as long as fuel is supplied. 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
