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.
What is claimed is: 1. A fuel cell system comprising one or more fuel cell assemblies and a heat transfer composition, the heat transfer composition comprising: (a) from about 20% to about 80% by weight of an alcohol; (b) from about 1% to about 90% by weight of a polyalkylene oxide; (c) from about 1% to about 30% by weight of an additive; and (d) balance being water; wherein said composition has an electrical resistance greater than about 5 KΩ·cm and wherein said composition is used in a fuel cell assembly. 2. The fuel cell system according to ...
