Hydrogen fuel cells have numerous applications, including powering homes and businesses and moving vehicles such as fuel cell powered cars, buses and trains. Some examples of fuel cell applications include the following: Power Fuel cells provide power for a wide range of commercial, industrial and household applications. These include everything from residential spaces to spacecraft and task force operations. Portable fuel cell systems can be used for various applications, from powering small devices to generating lots of power in remote regions. Mobile devices like laptops, for example, benefit from higher energy density and weight reductions over lithium-ion batteries. Fuel cells are very reliable because they don’t have any moving parts. There is also less than one minute of downtime per six years under ideal conditions, which equates to 99.9999% reliability of fuel cells. (5) Transport Fuel cells apply to a vast number of modes of transport. Because of the ability to generate immense power in a small device, a fuel cell electric vehicle could drive substantially further than an all-electric car. (6) Additionally, it is the most environmentally friendly fuel.
