A flush and fill process is used to ready a fuel cell cooling circuit for initial use. An external flushing system releasably connected to the cooling circuit circulates flushing coolant through the cooling circuit to remove contaminants from the wetted surfaces of the cooling circuit before the fuel cell is put into use. The flushing system includes a pump for circulating the flushing coolant through the cooling circuit, filters for removing contaminants from the coolant and a heater for elevating the temperature of the coolant. Following the flushing process to remove contaminants, the flushing system is disconnected from the cooling circuit and the cooling circuit is filled with fresh coolant.

The invention is a process for decomposing dried paint sludge to recover the organic and inorganic components of the paint sludge as gaseous, liquid, and composite materials. The process comprises drying the paint sludge to remove water and organic solvents, pyrolizing the dried paint sludge in an inert atmosphere in an elevated temperature of up to about 600.degree. C. to form gaseous and liquid decomposition materials and a solid residue. The process further comprises collecting the gaseous and liquid decomposition materials and subjecting the solid residue to sintering in an elevated temperate of about 900.degree. to 1300.degree. C. in an atmosphere of nitrogen, argon or ammonia to convert the solid residue to composite materials comprising barium nitranate and titanium compounds such as titanium dioxide, titanium nitride, and titanium carbide. The gaseous and liquid materials may be further pyrolyzed to carbon materials.
