"Given the efficiency and environmental benefits of emerging fuel cell technology, Boeing wants to be on the forefront of developing and applying it to aerospace products," said Francisco Escarti, BR&TE managing director. "The Fuel Cell Demonstrator Airplane project is an important step in that direction."
A fuel cell is an electrochemical device that converts hydrogen directly into electricity and heat without combustion. Fuel cells are emission-free and quieter than hydrocarbon fuel-powered engines. They save fuel and are cleaner for the environment. http://www.boeing.com/news/releases/2007/q1/070327e_nr.htmlinteresting to note teha the 787 is also retrofitable, which means that they can be fitted with the new technology if need be.
