The invention provides a quick response method and device for a solid oxide fuel cell stack, the solid oxide fuel cell stack is connected with an energy storage cell, and the method comprises the following steps: if the cell stack is not in a hot standby state, obtaining a difference power according to a real-time power and a required power; if the difference power is greater than 0 and the supplementable power is greater than the difference power, acquiring a first importance label of power supplementation; according to the first importance label, accessing an energy storage battery at a preset demand power change time point to output differential power to an external load until the differential power is 0; if the difference power is less than 0 and the absorbable power is greater than the difference power, acquiring a second importance label of power absorption; and accessing the energy storage battery at a preset demand power change time point according to the second importance label to absorb the differen
