Disclosed herein is an apparatus for controlling a fuel cell system, which includes multiple hot boxes including multiple fuel cell stacks, using a reconfigurable network having linear switching complexity, includes: a power conversion system for supplying outputs of normal stacks among the multiple fuel cell stacks to a load; at least one auxiliary power conversion system for supplying an output of at least one deteriorated stack among the multiple stacks to a load; a reconfigurable switch network for connecting in series or in parallel stacks of any hot box to stacks of another hot box; and a control unit for controlling an operation of the reconfigurable switch network by detecting a state of each of the stacks.

Apparatus and method for controlling fuel cell system using reconfigurable switch network

Disclosed herein is an apparatus for controlling a fuel cell system, including: a plurality of stack state detecting units for detecting respective states of a plurality of fuel cell stacks; a switching unit for connecting at least parts of the plurality of fuel cell stacks to each other in series or in parallel; and a control unit for detecting at least one degraded stack based on the states of the stacks detected by the plurality of stack state detecting units, and forming at least one degraded stack unit including the detected at least one degraded stack by controlling the operation of the switching unit, so the apparatus can quickly and easily connect the stacks to each other in series, in parallel or in series-parallel using cheap electric switches instead of using a plurality of power conditioning system (PCS).
