FUEL CELL POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a fuel cell power generation system which estimates heat demand from a hot-water storage tank to a user side.

SOLUTION: The system is provided with: a hot-water storage tank 3 storing hot water from a fuel cell 1; a plurality of thermometers 6 measuring temperature of hot water in the tank 3; and a estimating device 7 for estimating: an inner-tank calorie for each virtual divided space in the tank 3 based on ambient temperature and a cubic volume of the hot water in the tank 3; an inner-tank calorie for the tank as a whole from the sum of these; temperature measurement values of hot water at an inlet side and an outlet side of the fuel cell 1 and a cell exhaust heat volume based on the volume of the hot water in the fuel cell 1, and further, change of calorie in the hot-water storage tank per each predetermined time from the inner-tank calorie.
