摘要:
A cogeneration fuel cell system and associated methods of operation are provided that accommodate a demand for heat as well as a demand for electric power. The system is operated among various modes to balance heat and power demand signals. In general, a fuel cell system is coupled to a power sink and a heat sink, and a controller is adapted to respond to data signals from the power sink and the heat sink. As examples, such data signals from the heat sink may include a temperature indication or a heat demand signal (such as from a thermostat), and such data signals from the power sink may include a voltage or current measurement, an electrical power demand signal, or an electrical load.

An energy station includes a generating unit and a separate remotely located dispensing unit. In one aspect, the generating unit includes a housing having a reformer for generating reformate from a fuel stream, and a storage unit for storing the reformate. The dispensing unit includes a housing for dispensing reformate from the generating unit. The generating unit is located at a first location and the dispensing unit is located at a second location away from the first location. For example, the generating unit may be located outside the building and the dispensing unit may be located inside a garage. Also disclosed is a generating unit having an electrochemical cell, which may be operated as either a fuel cell for supplying electricity to the building or a hydrogen pump for purifying the reformate.
