The major reason fuel cells are more efficient than power sources based on combustion, says Charles Anderson, leader of the advanced engineering technology group at LANL, is that fuel cells avoid the Carnot-cycle limitations that come with an intermediate conversion to heat.
Compared to the ideal Carnot-cycle efficiency, which represents the processes in an ideal heat pump or engine, Sunpower's Stirling refrigerator exceeds an efficiency of 50 percent, which is competitive with today's machines.
