The 5kW UTC Power fuel cell system features simple vehicle interfaces, which allows for easy integration and installation, the company said.

UTC Power, a United Technologies company, has been working with BMW since 1999 to develop emission-free and freeze-capable fuel cell systems.

UTC said that the fuel cell system in its Series 1 vehicle represents the culmination of more than 10 years of development work on durability and freeze capability technology.

Ken Stewart, vice president of transportation business at UTC Power, said: “We have highly valued our relationship with BMW for over 10 years and we look forward to continuing our work on emission-free fuel cells that help BMW develop efficient, fun-to-drive vehicles for the marketplace.

“From a fully frozen state, the fuel cell is half way to full power in less than 30 seconds. The system uses UTC Power’s proprietary ambient pressure technology, which does not require a compressor to deliver air to the cell stack. This results in a quieter, more efficient system.”
