Research is going on vehicles powered by hydrogen (13). As compared to a battery, a fuel cell has to be refilled constantly with an “energy-rich” substance, such as pure hydrogen in a hydrogen-oxygen fuel cell. In hydrogen fuel cell, electricity is generated when electrochemical process occurs on combination of hydrogen gas and oxygen.
Hydrogen is often touted as the future of green energy, and the allure is clear. When burned or run through a fuel cell, the fuel produces water as exhaust, not carbon dioxide (CO 2). It is energy-rich enough to drive semitrailer trucks, cargo ships, and other heavy-duty vehicles that are tough to power with batteries.
