PROBLEM TO BE SOLVED: To enhance the operation efficiency of a fuel cell by accurately controlling the fuel supply to the anode or oxidant supply to the cathode. SOLUTION: In the operation method of the fuel cell comprising the anode, a fuel supply plate supplying fluid containing fuel to the anode, a cathode, an oxidant supply plate supplying fluid to the cathode, and an electrolyte interposed in between the anode and the cathode, at least one of the fuel supply plate and the oxidant supply plate is divided into a plurality of reaction chambers, the inlet of the fluid containing fuel or the oxidant and an outlet of the fluid containing the fuel or the oxidant are formed in each reaction chamber, a supply pump for supplying the fluid containing the fuel or the oxidant to the reaction chamber is installed at the inlet, a discharge valve for preventing back flow of the fluid, containing the fuel or the oxidant to the reaction chamber, is installed in the outlet, and the supply pump is driven by an optional pulse pattern.
