A fluid composition includes a coolant and a plurality of nanoparticles dispersed within the coolant. The plurality of nanoparticles includes glass, silica, pumices, metal compounds adapted to react with chloride in the coolant, and/or mixtures thereof. The plurality of nanoparticles substantially increases heat capacity of the coolant and enhances heat transfer efficiency of the fluid composition.

Fluid composition having enhanced heat transfer efficiency

The present invention relates generally to heat transfer compositions. More particularly, the present invention relates to heat transfer compositions with high electrical resistance for use in power-generating equipment or in engines. Such compositions are particularly useful in fuel cell assemblies.

Heat transfer compositions with high electrical resistance for fuel cell assemblies

A composition for sealing at least one fluid leak in heat exchange systems comprises at least one solvent, and fibrillated fiber in an amount and of a size sufficient to become entrained in and seal the one leak. At least one corrosion inhibitor is present in an amount sufficient to aid in prevention of corrosion of at least two metals. The corrosion inhibitor is compatible with coolants having organic acid corrosion inhibiting agents therein, and with coolants having silicate corrosion inhibiting agents therein.
