Hydrogen gas is supplied to the anode of the fuel cell. The anode is coated with platinum, which acts as a catalyst to break down the hydrogen into protons and electrons. If a circuit is connected between the anode and cathode then the electrons can travel through the circuit and provide power to any load that is connected as part of the circuit. Hydrogen does not occur naturally in the environment, hydrogen fuel must be derived from other substances that contain hydrogen such asmethanol, gasoline, natural gas, and water. Most hydrogen that is produced today comes from natural gas. If hydrogen is made from water the only byproduct is pure water. If fossil fuels are used as the original source of hydrogen there will be more by-products, such as carbon dioxide. When hydrogen is produced from water electricity is used to split the water molecule. If that electricity comes from a renewable energy source such as wind or solar power, then the resulting hydrogen is a renewable, zero emission fuel

Hydrogen Fuel Cell is the electrochemical cell, which converts the chemical energy into fuel through a series of redox reactions. The fuel cell can be an alternate energy source for vehicles, electric equipment, and other traditional technologies.

What are the advantages of hydrogen fuel cells?

  • Hydrogen fuel cells are healthy and have very low greenhouse gas emissions.

  • The fuel has high reliability, flexibility, and improved environmental quality.

  • The fuel cells can be used to develop renewable energy resources.

  • The fuel cell converts chemical energy to produce electrical energy. If hydrogen is a fuel source, then the products will be clean water, heat, and electricity.

Thus, hydrogen fuel cells are used to produce electricity and other sources of energy.
