What are the main uses of hydrogen fuel cells?

Hydrogen fuel cells are primarily used for power generation in vehicles, portable devices, and stationary systems.

Hydrogen fuel cells are a type of renewable energy technology that converts chemical energy into electricity. They are most commonly used in vehicles, such as cars and buses, to provide a cleaner alternative to fossil fuels. Hydrogen fuel cell vehicles (FCVs) use hydrogen gas to power an electric motor. Unlike conventional vehicles which run on petrol or diesel, FCVs emit only water, making them much more environmentally friendly.

In addition to vehicles, hydrogen fuel cells are also used in portable devices like laptops and mobile phones. These fuel cells can provide a longer-lasting power source compared to traditional batteries, making them an attractive option for these types of devices. They are also used in remote or hard-to-reach areas where it's difficult to establish a traditional power grid, such as rural areas or military bases.

Stationary systems, such as power plants and backup power systems, also utilise hydrogen fuel cells. In power plants, they can be used to generate electricity on a large scale, providing a renewable alternative to burning fossil fuels. For backup power systems, hydrogen fuel cells offer a reliable source of power in case of an outage. They can also be used in buildings to provide heat and electricity, reducing reliance on the grid and lowering carbon emissions.

In summary, hydrogen fuel cells are a versatile technology with a wide range of applications. From powering vehicles to providing electricity for portable devices and stationary systems, they offer a sustainable and efficient energy solution.
