In this process, hydrogen combines with oxygen on the anode of the fuel cell and generates electricity with water. The main components of the fuel cell consist of the anode, cathode and electrolyte membrane. Hydrogen fuel cells are an environmentally friendly energy source as they operate emission-free and produce only water vapor. They are used in many application areas such as electric vehicles, portable power supplies and stationary energy systems. Thanks to their high efficiency and low environmental impact, they play an important role in sustainable energy solutions by reducing dependence on fossil fuels. Proton exchange membrane (PEM) fuel cells are a widely preferred type due to their high energy density and fast start-up characteristics.
