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.

摘要： A cooling system for a fuel cell includes a heat exchanger for cooling coolant discharged from the fuel cell and a heat regulator for adjusting a temperature of coolant to be supplied to the fuel cell after mixing coolant that has been cooled by the heat exchanger with coolant that has bypassed the heat exchanger together. The cooling system also includes an ion exchanger for removing ions from the coolant with the use of ion exchange resin, and a supply control means for controlling coolant to be supplied to the ion exchanger. The supply control means supplies the ion exchanger with coolant that has bypassed the heat exchanger when the heat regulator operates beyond a coolant temperature adjustable range, and the supply control means supplies the ion exchanger with coolant that has been cooled by the heat exchanger when the heat regulator operates within the coolant temperature adjustable range.

摘要： Before warmup of a fuel cell stack (1) is complete, a cooling water pressure of the fuel cell stack (1) is suppressed lower than the pressure used when the fuel cell system is run in the steady state. In this way, when the system is started from a low temperature state, water in a cathode (2) and anode (3) flows efficiently into the cooling water passage (9), and water clogging is prevented while maintaining a proper water balance in the fuel cell system.
