Novel chemical base for fuel cell engine heat exchange coolant/antifreeze

摘要

A nontoxic fuel cell engine coolant which has an electrical resistivity of greater than 250 kOhm-cm, a boiling point of greater than 90° C., a freezing point of less than -40° C., a thermal conductivity of greater than 0.4 W/m-k, a viscosity of less than 1 cPs at 80° C., a viscosity of less than 6 cPs at 0°C., a heat capacity of greater than 3 kJ/kg-K, and which is compatible with current cooling system materials.
