Introduction to Fuel Cells: Advantages and Disadvantages

The video discusses fuel cells, which use hydrogen as fuel and react it with oxygen to produce only water, hence not emitting any greenhouse gases. Several methods of producing hydrogen, including steam reforming and electrolysis, are explained along with their carbon footprint. The disadvantages, including high flammability, expensive purchase price, and the limited availability of hydrogen filling stations, are also discussed. The video provides insight into the working of fuel cells, their applications, and their potential impact on the environment.
