A fuel cell cogeneration system comprises a fuel cell (1), a cooling system for the fuel cell, a heater (100), a heat utilization portion configured to store heat recovered in the cooling system to allow the heat to be consumed, a detector configured to detect calories remaining in the heat utilization portion (101A-101C), and a controller (201), wherein the controller determines whether or not the calories remaining in the heat utilization portion are at least not less than the calories required to increase the temperature of the fuel cell (1) to the operating temperature, and based on determination, increases the temperature of the fuel cell to the operating temperature by supplying the remaining calories to the fuel cell through the cooling system and/or by heating the cooling water in the cooling system by the heater (100). |
