PROBLEM TO BE SOLVED: To provide a fuel battery system that has a long lifetime and is stable for a long term.SOLUTION: A fuel battery system 1 is a fuel battery system having a direct methanol type fuel battery 2, and includes a fuel tank 3 in which liquid fuel containing methanol is stored, a methanol supply device 4 for supplying methanol to the fuel tank, a liquid concentration sensor 5 for measuring the methanol concentration of the liquid fuel stored in the fuel tank, a current sensor 6 for measuring the output current value of the fuel cell, and a control device 7 for controlling the supply amount of methanol to the fuel tank. The control device controls the methanol supply device based on the output current value measured by the current sensor, and corrects the supply amount of methanol by the methanol supply device based on the measured value of the liquid concentration sensor at regular time intervals.SELECTED DRAWING: Figure 3 |
