Performance of thermoelectric (TE) modules for the TE power conversion system combined with open rack type LNG vaporizer (ORV) is discussed. Most of the conventional BiTe TE modules suffer sudden decrease of the power at cryogenic temperature as low as -160°C. This is called as Mayer-Marschall effect. Authors investigated the cause of this effect and found TE modules that could avoid such effect. Performance data of such TE modules obtained at the cryogenic thermoelectric (CTE) test rig which could realize temperature and fluid dynamic condition of the ORV is presented.
