The invention discloses a rapid activation method for a fuel cell stack. The rapid activation method is characterized by comprising the following steps: S1, mounting the fuel cell stack on a stack test bench and completing connection; through the test bench, nitrogen is firstly introduced into the anode side of the fuel cell stack to expel air in an anode flow channel, and then anode fuel is introduced; a cathode oxidizing agent is introduced into the cathode side; s2, fuel is introduced according to the set fuel stoichiometric ratio introduced from the anode side to the cathode side; s3, enabling the fuel cell stack to run under the set first monomer working voltage; s4, monitoring the power of the fuel cell stack in real time, reducing the single working voltage after the power is stable, and simplifying the operation of the fuel cell stack under the second single working voltage; and S5, repeating the steps S1 to S4 for a plurality of times to finish activation. The method has the advantages that the stabl
