APPARATUS AND METHOD FOR DETERMINING THE THERMAL CONDUCTIVITY OF A FLUID

摘要

The invention relates to an apparatus (10) for determining the thermal conductivity of a fluid, in particular of a service fluid for a fuel cell, having a feed means (14), by means of which the fluid may be fed to a main body (12), with which there are associated a temperature sensor (24) for measuring and a temperature control element (22) for adjusting the temperature of the main body (12), wherein a further temperature sensor (26) for measuring the temperature of the fluid in the feed means (14) is provided for detecting the presence of a liquid phase in the fluid. The invention further relates to a method for determining the thermal conductivity of a fluid.
