A fuel cell is a device that generates electricity by a chemical reaction. Every fuel cell has two electrodes, one positive and one negative, called, respectively, the anode and cathode. The reactions that produce electricity take place at the electrodes.

Every fuel cell also has an electrolyte, which carries electrically charged particles from one electrode to the other, and a catalyst, which speeds the reactions at the electrodes.

Hydrogen is the basic fuel, but fuel cells also require oxygen. One great appeal of fuel cells is that they generate electricity with very little pollution, much of the hydrogen and oxygen used in generating electricity ultimately combine to form water.

Fuel cells offer a unique combination of benefits that make them a vital technology ideally suited for a number of applications. From high efficiency to scalability, fuel cells provide a distinct advantage over incumbent energy generation technologies, which is why top companies, governments, and the military are adopting fuel cells for everyday use.

Benefits that fuel cells provide:
• Low-to-Zero Emissions
• High Efficiency
• Reliability and High Quality Power
• Fuel Flexibility
• Energy Security
• Ruggedness and Durability
• Scalability
• Quiet Operation
• Technology Compatibility
• Lightweight and Long Lasting
