H2 Hydrogen Fuel Cells DOE Hydrogen Program Overview the fuel’s energy — corresponding to more than a 50% reduction in fuel consumption, compared Hydrogen is a versatile energy carrier that can be used to a conventional vehicle with a gasoline internal to power nearly every end-use energy need. The fuel combustion engine. cell — an energy conversion device that can efficiently capture and use the power of hydrogen — is the key to 4In addition, fuel cells operate quietly, have fewer making it happen. moving parts, and are well suited to a variety of applications. 4Stationary fuel cells can be used for backup power, power for remote locations, distributed power generation, and cogeneration (in which excess How Do Fuel Cells Work? heat released during electricity generation is used A single fuel cell consists of an electrolyte sandwiched for other applications). between two electrodes, an anode and a cathode. Bipolar 4Fuel cells can power almost any portable application plates on either side of the cell help distribute gases that typically uses batteries, from hand-held devices and serve as current collectors.
