Definition: ratio of total useable energy flow (net electric power and recovered heat flow) to the total enthalpy flow supplied to the fuel cell power system

Note 1 to entry: The supplied total (including reaction enthalpy) enthalpy flow of the raw fuel should be related to the lower heating value (LHV) for a better comparison with other types of energy conversion system.
