Abstract

Coolant compositions for fuel cells having at least one sugar alcohol in a base component that resist oxidation of the base component and the rise of the electric conductivity of the coolant when the fuel cell is in use. Fuel cells including coolant compositions having at least one sugar alcohol in a base component. Methods of making fuel cells including coolant compositions having at least one sugar alcohol in a base component.

Description

technical field [0001] The present invention relates to a fuel cell, particularly to a coolant composition used in the cooling of a fuel cell for automobiles, and in more detail to a composition that, even after long-term use, increases the electrical conductivity due to the oxidation of the base agent, and after a long period of time A fuel cell coolant composition that can still maintain low electrical conductivity. Background technique [0002] A fuel cell is generally a battery pack formed by laminating multiple layers of individual cells as power generation units. Since the battery pack generates heat during power generation, cooling plates are inserted every few batteries in order to cool the battery pack. A coolant passage is formed inside the cooling plate, and the battery pack is cooled by the coolant flowing through the passage. [0003] In this way, since the fuel cell coolant circulates in the battery pack that generates electricity to cool the battery pack, if...
