摘要： A power source system (1) includes a fuel cell (40) and a battery (20) connected in parallel. A DC-DC converter (30) is connected to the battery (20) side. A maximum output ratio of the fuel cell (40) and the battery (20) is set in a range in which the output of the fuel cell falls within 65 to 80% of the total output. Accordingly, electric power loss due to the DC-DC converter (30) is controlled, whereby a high energy efficiency can be achieved.

摘要： An AC impedance meter 200 measures an AC impedance of fuel cells 100 against at least a specific frequency. A sensor group 300 detects at least one operating condition of the fuel cells 100. A detection unit 400 compares a degradation reference value corresponding to the detected operating condition with a resistance value led from the measured AC impedance and detects performance degradation in the fuel cells 100 based on a result of the comparison. This arrangement enables easy detection of performance degradation in the fuel cells, irrespective of a variation in operating condition of the fuel cells.
