Abstract

There is provided a cooling system for an electrochemical reactor that generates electrical energy and heat energy, wherein the reactor operates at a reactor temperature. The cooling system includes a coolant circulating in direct or indirect thermal contact with the reactor at a coolant pressure, The coolant is a liquid having a dielectric constant, at the realtor temperature and coolant pressure, of less than about 10; a resistivity while circulated, in either direct or indirect thermal contact with the reactor of greater than 10<SP>3</SP> Ohm-cm; and a boiling point above the reactor temperature at the reactor pressure so that the coolant absorbs and removes excess heat energy from the reactor via sensible heat transfer to the coolant and the coolant remains in its liquid phase after absorbing the excess heat energy. The dielectric nature of the coolant prevents it from dissolving and attracting ions from the parent system, thersby allowing it to maintain its resistivity over extended periods of use. Preferably, the liquid is a composition having at least one hydrofluoroether, at least one hydrofluorocarbon, or an azeotrope or azeotrope-like mixture of hydrofluoroethers and/or hydrofluorocarbons.
