Fuel cell technology is a method of generating electricity through a chemical reaction, typically between hydrogen and oxygen. In this process, hydrogen gas is fed into the fuel cell, where it reacts with oxygen from the air. This reaction produces electricity, water, and heat, making it a clean energy source with minimal environmental impact. Fuel cells are used in various applications, including automobiles, portable electronics, and stationary power generation. They offer advantages such as high efficiency and low emissions compared to traditional combustion engines. As the demand for sustainable energy solutions grows, fuel cell technology is gaining attention as a viable alternative.
