A fuel cell system and method of controlling the fuel cell system are provided. The fuel cell system includes a fuel cell stack that is configured to receive fuel, and generate electric energy and a fuel supply valve that is configured to adjust pressure of fuel that is supplied to the fuel cell stack. A controller is configured to operate the fuel supply valve to supply fuel of predetermined target pressure to the fuel cell stack, using a difference between the predetermined target pressure and actual pressure of the fuel being supplied. When the actual pressure reaches a steady state from a transient state, the controller applies a smaller gain than in the transient state to determine a first controlled variable based on the difference between the target pressure and the actual pressure of the fuel being supplied.
