Source sentences:
text: Efficiencies can be as high as 65% when the fuel cell is paired with a turbine, and 85% if heat is captured and used in a combined heat and power (CHP) system.
text: For the chemical reactions involved in fuel cells the maximum theoretical efficiency is over 85% which is between two and three times the typical efficiency of a heat engine.
