초록

The invention is a water retention system for a fuel cell power plant having at least one fuel cell and a coolant loop with a coolant reservoir and coolant passages for directing a coolant fluid through the fuel cell. An air conditioning unit is provided for directing a refrigerant to a first heat exchanger that cools secondary process air and for directing water condensed from the secondary process air to the coolant reservoir. The air conditioning unit also directs the refrigerant to a second heat exchanger that cools the coolant fluid within the coola...
