UTC Power has installed 260 stationary fuel cell power plants for customers in 19 countries on five continents. Its PureCell system produces 200 kilowatts of electric power plus about 870,000 Btu/hour of heat for combined heat and power applications. The company is now developing a next-generation phosphoric acid fuel cell stack for commercial on-site power applications that will deliver a 10-year operating life, 400 kilowatts of power and more than 1.6 million Btu/hr of thermal output for combined heat and power applications.

"For on-site power applications, the UTC Power PureCell phosphoric acid system is the demonstrated leader in durability," said Jan van Dokkum, UTC Power president. "No other company can come close to matching our 8 million hours of operation."

UTC Power's PureCell system meets the strictest emissions standards in the United States, namely those established by the California Air Resources Board for 2007. Hydrogen fuel and oxygen from the air are combined in the fuel cell to produce electricity, heat and water. When used in combined heat and power applications, fuel cells can perform at nearly three times the energy efficiency of the electrical grid.

Earlier this year, UTC Power was selected to provide a PureCell fuel cell to Fujitsu America to power and heat a portion of its Silicon Valley Campus in California. Other customers have put UTC Power fuel cells to work at college campuses, telecommunications centers, data centers, hospitals, office buildings and hotels.
