What Are Hydrogen Fuel Cells?
Hydrogen fuel cells are devices that convert hydrogen into electricity through a chemical reaction, with water vapor as the only byproduct. There are different types of fuel cells, each with its own advantages and applications in various industries.
Process of converting hydrogen into electricity
Fuel cells generate power by fusing hydrogen and oxygen atoms. This happens through a chemical reaction rather than combustion, making the process clean with only water as a byproduct.
Inside each fuel cell, hydrogen gas is channeled towards an anode while oxygen heads to the cathode. The electrolyte that separates these two sides allows electrically charged particles to pass but not the gases themselves.
As hydrogen atoms reach the anode, they encounter a catalyst which causes them to split into electrons and protons. The electrons then travel through a circuit, creating electricity that can power anything from small devices to large vehicles.
After powering up necessary applications, these electrons return to combine with oxygen and previously separated protons at the cathode side, forming nothing more than water vapour.
This cycle continues as long as there is a supply of hydrogen fuel, providing sustainable energy without carbon emissions or other pollutants.
Types of fuel cells
After understanding the process of converting hydrogen into electricity, it’s important to explore the different types of fuel cells.
- Proton Exchange Membrane (PEM) Fuel Cells: These fuel cells are commonly used in transportation and stationary power systems due to their low operating temperature and quick start-up time.
- Solid Oxide Fuel Cells (SOFC): Known for their high efficiency and ability to operate on various fuels, SOFCs are suitable for large-scale power generation applications.
- Molten Carbonate Fuel Cells (MCFC): These fuel cells excel at high-temperature operation, making them ideal for industrial applications and combined heat and power systems.
- Alkaline Fuel Cells (AFC): AFCs are primarily used in space missions as they require pure hydrogen and oxygen input gases, which limits their terrestrial application.
- Phosphoric Acid Fuel Cells (PAFC): With good efficiency levels, these fuel cells find usage in commercial and industrial settings due to their ability to produce both electricity and heat.
Advantages and Challenges of Hydrogen Fuel Cells
Hydrogen fuel cells offer the advantage of zero emissions and high energy density, making them a clean and efficient source of power. However, challenges in production and storage need to be addressed for widespread adoption.
