Page "Fuel cell" Paragraph 8

United Technologies Corporation's UTC Power subsidiary was the first company to manufacture and commercialize a large, stationary fuel cell system for use as a co-generation power plant in hospitals, universities and large office buildings.

UTC Power marketed their fuel cell, the PureCell 200, a 200 kW system, now replaced by a 400 kW version, the PureCell Model 400.

UTC Power continues to be the sole supplier of fuel cells to NASA for use in space vehicles, having supplied fuel cells for the Apollo missions, and the Space Shuttle program, and is developing fuel cells for automobiles, buses, and cell phone towers.

The company has demonstrated the first fuel cell capable of starting under freezing conditions with its proton exchange membrane.
