Fuel Cell

A fuel cell is a device that generates electricity through a chemical reaction, typically involving hydrogen and oxygen. Unlike batteries, which store energy, fuel cells produce electricity continuously as long as they have a fuel supply. The process combines hydrogen with oxygen from the air to produce electricity, water, and a small amount of heat. Fuel cells are efficient, environmentally friendly, and can be used in various applications such as vehicles, power plants, and portable devices, offering a clean alternative to traditional fossil fuel-based energy sources.
