A 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 kOm-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 mPa.s (1 cPs) at 80~ C, a viscosity of less than 6 mPa.s (6 cPs) at 0~ C, a heat capacity of greater than 3 kJ/kg-K, and which is compatible with current cooling system materials.
