Current free double layers are found in plasmas with two-temperature electron populations. A model of the expansion of this type of plasma in a Laval nozzle is presented. Stationary double layers form for a limited range of plasma parameters. They can be located either on the divergent nozzle, or the throat, or the convergent nozzle; in the two last cases, a non-neutral spatial rippling remain downstream of them. Relative gains in plasma propulsion parameters are found for moderately low values of hot electron density; gains tend to be larger when electrons are hotter and for larger nozzle expansion ratios. Both propulsion gains and double layer formation are associated to the anomalous thermodynamic properties of the plasma.
