PURPOSE: A fuel cell stack is provided to enhance performance and durability of the fuel cells by equally maintaining fluid pressure of the fuel. CONSTITUTION: A fuel cell stack(1) comprises a differential pressure gauge(40) which measures pressure difference of one end of and the other end of manifold(20) for fuel supply, a stack entrance(50) and a stack exit(55) which are respectively formed in the front end plate(30), a connection pipe(60) which is connected to a rear surface end plate(35) in which the side of the stack entrance and a manifold(25) for the fuel exhaustion are in touch, a variable valve(70) for controlling fluid flow inside a connection pipe, and a controller(80) which controls the variable valve.
