When the AC line (11) of one local system (10A) and a power system (1) are in the parallel-off state, a control device (C) included in a power supply system (S) causes the local inverter devices (13) of the local systems (10) to operate in a parallel-off operation mode in which control is performed such that the voltage of power on the AC line (11) is at a target voltage and such that the frequency of power on the AC line (11) is at a target frequency determined according to the state of charge of a power storage device (12). When a condition for switching to the connected state has been satisfied, the control device (C) stops operation of the local inverter device (13) in the parallel-off operation mode and causes a switch to the connected state by operating the interrupting device (2), and thereafter causes the local inverter device (13) to operate in a charging operation mode used in charging the power storage device (12) with supplementary power received from the power system (1).

To reliably detect the abnormality of a recycle fuel pipe that returns a part of fuel reformed by a reforming unit to a desulfurizer and suppress the degradation of the reforming unit and the failure of a fuel cell due to a sulfur component. Provided is a fuel cell system in which a recycle gas pipe 39 is provided with a temperature sensor 39a which directly detects the temperature of a recycle gas and a control device 15 detects the passage and/or the flow rate of the recycle gas passing through the recycle gas pipe 39 based on the temperature of the recycle gas detected by the temperature sensor 39a (a detection portion: step S108).


For implementing a reforming reaction such as steam reforming or autothermal reforming, to obtain hydrogen, carbon monoxide, carbon dioxide, methane, etc. by bringing hydrocarbons and steam into contact with a reforming catalyst, an arrangement is provided to enable reforming of the hydrocarbon to proceed under a stable condition for an extended period thanks to high sulfur resistance thereof. The arrangement employs a reforming catalyst supporting both platinum and iridium on an inorganic oxide support for the reforming of the hydrocarbon.


Provided is a granular activated carbon having many mesopores that can be used for applications similar to zinc chloride-activated carbons, and also provided is a method for manufacturing the same.
