Fuel cells: hydrogen fuel cells comprise a third category of energy storage system. In a hydrogen fuel cell, hydrogen and oxygen molecules are combined to produce heat and water.. A fuel cell uses the chemical energy of hydrogen or other fuels to cleanly and efficiently produce electricity. If hydrogen is the fuel, the only products are electricity, water, and heat. The IRS permits hydrogen storage (whether as a compressed or liquefied gas or chemical storage in ammonia or methanol). . Tanker trucks replenish liquid hydrogen (LH2) within large sphere at NASA's Kennedy Space Center in Florida, Launch Pad 39B. Thank you for your attention. . Fuel cells are most commonly applied in standalone power generation systems and vehicle energy sources because of their unique features of high efficiency, wide size range, modularity, and compatibility with cogeneration. The development of a complete fuel cell energy system requires a basic. . ell reaction to provide electricity when neede ries,PV Solar Cells,Hydrogen Storage Devicesetc. In this paper,the efficiency and shortcoming of various energy storage devices are discussed. In fuel cells,electrical energy is g y and converts it to el ical energy through a controlled redox reaction.
