H2 Revolution
Fuel cell catalysts are materials that facilitate the chemical reactions occurring in fuel cells to convert chemical energy into electrical energy. Specifically, they promote the reactions of hydrogen and oxygen gases, which combine to produce water and electricity in an electrochemical process. In a fuel cell, the catalyst is crucial for both the anode and cathode reactions—where hydrogen oxidation and oxygen reduction take place, respectively. Catalysts often include precious metals such as platinum, although research is ongoing to find more cost-effective alternatives. The efficiency, durability, and overall performance of fuel cells heavily depend on the properties of the catalysts used, including their surface area, electronic conductivity, and chemical stability. Effective catalysts enhance the reaction rates and lower the energy barriers, thereby improving the overall efficiency of fuel cell systems, which are used in various applications, from powering vehicles to providing stationary energy.
