    摘要: The invention is a pressurized water recovery system for a fuel cell power plant including at least one fuel cell having an electrolyte between anode and cathode electrodes for producing an electric current from a reducing fluid and an oxidant stream. A coolant loop directs a coolant fluid from a reservoir through a coolant passage to the fuel cell and back to the reservoir, and the coolant loop also receives coolant fluid through water lines secured between condensing heat exchangers and the coolant reservoir. A process exhaust passage directs a process exhaust stream from adjacent the cathode and anode electrodes out of the fuel cell and into a condensing heat exchanger. Whenever the power plant is under coolant stress, a process exhaust valve selectively directs a portion of the process exhaust stream out of the process exhaust passage to a supercharger that pressurizes the received portion of the process exhaust stream and directs the pressurized portion to a pressurized condensing heat exchanger. Because the process exhaust stream within the pressurized heat exchanger is under pressure, an increased amount of water condenses out of the stream without a need to continuously pressurize any of the fuel cell components. The increased amount of condensed water is directed to the coolant reservoir, and whenever the coolant stress ends, the process exhaust valve and supercharger stop pressurizing any portion of the process exhaust stream.

    摘要: A power plant for the generation of electricity utilizes high temperature fuel cells, such as molten carbonate fuel cells, as its main power supply. Part of the oxidant exhaust stream from the fuel cell is recycled through the fuel cell. Waste energy from the fuel cell in the form of exhaust gases, such as part of the oxidant exhaust, drives a turbocharger for compressing the oxidant used in the fuel cell. In a preferred embodiment the oxidant exhaust also is the source of energy for powering a bottoming cycle, such as a steam driven turbogenerator. Power plant efficiency is improved by making maximum use of the energy and heat generated within the system.
