Fuel cell electric vehicles (FCEVs) are similar in operation to BEVs except for the source of energy. Hydrogen fuel and the fuel cell replace the battery. The process of conversion is taken place by taking compressed hydrogen from the vehicle-mounted tank and mixing it with the atmospheric air that produces DC electricity to drive the electric motor and the …

Fuel cells work like batteries, but they do not run down or need recharging. They 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 ...

Introduction. A flow battery is a fully rechargeable electrical energy storage device where fluids containing the active materials are pumped through a cell, promoting reduction/oxidation on both sides of an ion-exchange membrane, resulting in an electrical potential. In a battery without bulk flow of the electrolyte, the electro-active ...

How Hydrogen Storage Works. Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is − ...
