Now, let's see how they can be used in aviation propulsion. Fuel cells offer higher energy efficiency with no emissions when compared to existing piston and turbine powerplants. A fuel cell uses hydrogen and oxygen as the source of energy. Under the Zero CO project, a recent feasibility study was performed on fuel cell powered light aircraft. The project's goal was two-fold: to drastically reduce or eliminate the environmental impact of subsonic air breathing propulsion system as a source of global climate change by reducing CO emissions from present day levels to zero while concurrently reducing nitrogen oxide (NOx) emissions by more than a factor of five over present day levels. Both goals were aimed at reducing stress upon the earth's ozone layer. | |
