Abstract

Device and method for controlling fuel cell stack connection. The device includes fuel cell stacks and a power conditioning unit connected to the stacks, and further includes: a memory storing a first critical value by which the connection control device starts an operation, second critical values ranging from zero to the first critical value, and a boundary value for placing the second critical values in at least two subsidiary ranges; stack voltage sensing units for sensing voltages of the stacks; and a control unit for determining whether sensed voltages have been reduced to the first critical value or greater, and starting to control the operation of a switching unit when any one of the sensed voltages has been reduced to the first critical value or greater, thereby placing one or more stacks having voltages associated with each one of the at least two subsidiary ranges in one of individual groups.
