1. A method of distributing power in a fuel cell system including a plurality of fuel cell stacks, the method comprising:
determining, by a controller, a total system power demand, which is a power demand of the fuel cell system;
determining, by the controller, an operation order of the fuel cell stacks based on a state of the fuel cell stacks;
determining, by the controller, a number of operation fuel cell stacks, which is a number of fuel cell stacks to be operated, among the plurality of fuel cell stacks, based on the total system power demand and an average available power of the fuel cell stacks;
determining, by the controller, operation target fuel cell stacks, the operation target fuel cell stacks being fuel cell stacks to which the total system power demand is to be distributed, based on the operation order of the fuel cell stacks and the number of the operation fuel cell stacks; and
determining, by the controller, a power demand of each of the operation target fuel cell stacks based on the total system power demand and an effective catalyst reaction area ratio of each fuel cell stack included in the operation target fuel cell stacks.
