摘要：
A cleaner-passivator composition and method for treating a fuel cell cooling system are described. The cleaner-passivator comprises a complexing agent, a surfactant, a corrosion inhibitor, and a solvent. The cleaner-passivator reduces the contaminants circulating in the fuel cell coolant system that contribute to increasing conductivity in the fuel cell coolant. In addition, the passivator reduces the surface corrosion in the fuel cell system.
