Abstract
Excess or waste water produced by the operation of a fuel cell power plant is discharged directly into the ambient environment by a discharge system which ensures that only the cleanest water in the system can be discharged. The discharge system is controlled by the amount of water in the power plant water storage tank. The storage tank receives contaminated water from the power plant, and also receives clean water from demineralizing beds. When the quantity of water in the storage tank exceeds a predetermined amount, the clean incoming water from the demineralizing beds is diverted into a drain passage where it is drained from the power plant. The drainage of clean water stops when the amount of water in the storage tank drops below the predetermined amount.
