Hydrogen fuel cells are an alternative source that can be used in a variety of applications. A fuel cell is a device that converts the chemical energy of joining hydrogen molecules with oxygen molecules from the surrounding air into electrical energy.

FREMONT, CA: The element hydrogen is considered the fundamental building block of the universe because it is the simplest and most abundant element known to us. Hydrogen is most frequently found on Earth in combination with oxygen in the form of water, covering 71 percent of the planet's surface, and is an essential element for all forms of life.

Hydrogen is proving to be a key component in our global efforts to decarbonize electricity, heating, transportation, and industrial processes because it is versatile and environmentally friendly when generated from renewable energy. Hydrogen can be stored and transported safely. It can be mixed with other fuels or used to make hydrocarbon fuels. It has become an integral part of the world's current alternative power landscape thanks to decades of innovation. Fuel cell and hydrogen technologies are used by companies to power various applications, including transit buses, delivery trucks, semi-trucks, and passenger trains, to name a few.

Hydrogen fuel cells are an alternative source that can be used in a variety of applications. A fuel cell is a device that converts the chemical energy of joining hydrogen molecules with oxygen molecules from the surrounding air into electrical energy. Heat and water are produced as a byproduct of this reaction, which exits the system as water vapor.

The electricity produced by the flow of electrons in the fuel cell can be used to drive an electric motor, produce mechanical power, drive accessories, and charge high-voltage battery packs in Fuel Cell Electric Vehicle (FCEV) powertrains. The electric voltage can be increased by stacking several fuel cells together, and more current and thus more power for the application can be obtained by feeding more air and hydrogen to the cells or increasing the active surface area of the cells.

The stack, and Balance of Plant (BoP) subsystems such as fuel, air, and water management, and coolant control hardware and software, are all housed in a module. The fuel cell module can then be integrated into a full-electric power system with radiators, hydrogen storage tanks, power electronics, and hybrid batteries that can be used in different applications.
