摘要:
A fuel cell system (100) includes: a fuel cell (60) that generates power using an oxidant gas and a fuel gas; estimating means (10) for estimating an electric resistance of the fuel cell in accordance with a voltage and a current of the fuel cell; and temperature controlling means (10) for performing control to raise a temperature of the fuel cell when the electric resistance estimated by the estimating means exceeds a target electric resistance range and reduce the temperature of the fuel cell when the estimated electric resistance falls below the target electric resistance range.
摘要:
A control apparatus includes a control unit which instructs a constant temperature mode to the fuel cell unit as one of operation modes, the constant temperature mode being a mode for performing an control to cover power consumption of the auxiliaries by power supplied from the outside and an control to keep a temperature of the power generation unit constant within a prescribed temperature range. In the constant temperature mode, power output from the power generation unit is at least smaller than the power consumption of the auxiliaries.

An EMS (200) controls: a fuel cell unit (150) which comprises a cell stack (151B) which generates power by chemical reaction, and auxiliaries; and a storage cell unit (140) which comprises a storage cell (141). The EMS (200) comprises: a control unit (230) which instructs the fuel cell unit (150) to enter one operation mode among a power generation mode and a temperature maintenance mode, said power generation mode being a mode wherein power generation is aggressively performed by the cell stack (151B), and said temperature preservation mode being a mode wherein control is performed so that power consumption by the auxiliaries is covered by power supplied from an external source and so that the temperature of a power generation unit is kept within a predetermined temperature range. If, when charging the storage cell (141), the unit price of electricity from a grid falls below a predetermined value, the control unit (230) controls the fuel cell unit to operate in the temperature maintenance mode.

摘要:
A cell stack device includes a cell stack, a holding member, and a positive electrode terminal. The cell stack is constructed by stacking a plurality of cells. The holding member holds the cells. The positive electrode terminal functions as a positive electrode when power generated by the cell stack is output to the outside. Furthermore, the potential of the positive electrode terminal is not more than that of the holding member.
摘要:
An EMS (200) is provided with a control unit (230) for instructing a fuel cell unit (150) to operate in one of operation modes including an idling mode for performing a control to cover power consumption of auxiliaries by power other than grid power, and a constant temperature mode for performing a control to cover the power consumption of the auxiliaries by power supplied from the outside and keep a temperature of a cell stack (51B) within a predetermined temperature range. When a power failure occurs while the fuel cell unit (150) is operating in the constant temperature mode, the control unit (230) controls the fuel cell unit (150) to operate in the idling mode.
