611 Technology Development and Barriers

Fuel cells have been shown to provide electricity from both hydrogen and fossil fuels at efficiencies greater than any other electric generating device. Emissions from fuel cells have been shown to be near zero for most pollutants of concern (e.g., NOx, SOx, CO, and hydrocarbons) depending upon the specific fuel cell technology and application. Fuel cells are scalable down to very small sizes while maintaining extraordinary fuel efficiency and environmental sensitivity. So why are fuel cells not playing a major role in today's market, and why do some experts not expect them to become widely utilized until at least ten years from now? There are several reasons, each of which is a critical and current area of research, development, and demonstration for fuel cell technologies.
