What is a hydrogen fuel cell?
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.
What are the advantages of hydrogen-based solid-state batteries and fuel cells?
This breakthrough means that the advantages of hydrogen-based solid-state batteries and fuel cells are within practical reach, including improved safety, efficiency, and energy density, which are essential for advancing towards a practical hydrogen-based energy economy.The study was published in the scientific journal Advanced Energy Materials.
In hydrogen fuel cell, electricity is generated when electrochemical process occurs on combination of hydrogen gas and oxygen. In this reaction heat and water vapor are the byproducts. Figure 2. Components of hydrogen fuel cell.
For hydrogen-based energy storage and fuel to become more widespread, it needs to be safe, very efficient, and as simple as possible. Current hydrogen-based fuel cells used in electric cars work by allowing hydrogen protons to pass from one end of the fuel cell to the other through a polymer membrane when generating energy.
