摘要： PROBLEM TO BE SOLVED: To provide a fuel cell power source device capable of always supplying highly-efficient power in spite of variation of loads. SOLUTION: A measured value of a monitoring target is obtained (step 403), and average power consumption of the load is calculated (step 404). Further, it is determined whether or not the average power consumption of the load is in a designated normal range (step 405), and the total value of the average power consumption of the load and power consumption normally consumed by a fuel cell internal auxiliary device is calculated when determining that it is within the normal range. Furthermore, it is determined whether or not the total consumption power is larger than a power generation output P1 when it becomes designated power generation efficiency T1 (step 407), and when the total power consumption is larger than the power generation output P1, this step returns to the step 402 in order to repeat the treatment. Then, when determining that the total power consumption is smaller than the power generation output P1, a new output setting value is set up by increasing 100W to the output setting value (step 408), a step returns to the step 402 in order to repeat the treatment.
