摘要： In the fuel cell (FC) system comprising a FC and a rechargeable battery, a demand power of the FC is calculated by subtracting the charge power to the battery from a demand power signal which indicates the demand value of a load current and using the result. Accordingly, the charge current is never supplied to the battery which is charged to the maximum ratio, which prevents the utilization ratio of the fuel cell from decreasing and which prevents the battery from overcharge. On the other hand, the battery which is discharged to the minimum ratio does not output the discharge power but the charge power is supplied to the battery. Accordingly, it prevents the battery from over discharge.
摘要翻译：在包括FC和可再充电电池的燃料电池（FC）系统中，通过从指示负载电流的需求值的需求功率信号中减去对电池的充电电力来计算FC的需求功率，并且使用该结果。因此，不会将充电电流供给到充电到最大比例的电池，从而防止燃料电池的利用率下降，并且防止电池过充电。另一方面，放电到最小比例的电池不输出放电电力，而是向电池供给充电电力。因此，防止电池过度放电。

摘要： In a fuel cell system, regeneration-time voltage fixed control is implemented where during regeneration or when regeneration is expected to occur, output voltage of a fuel cell is set to a voltage value outside an oxidation reduction progress voltage range, and the amount of reactant gas supplied to the fuel cell is changed based on the amount of electric power remaining in an energy storage device. In the regeneration-time voltage fixed control, it is determined whether or not regeneration occurs while a moving body equipped with the fuel cell system is moving down a slope, and in the case where it is determined that regeneration occurs while the moving body is moving down a slope, the amount of the reactant gas supplied to the fuel cell is decreased in comparison with the case where it is determined that regeneration occurs while the moving body is not moving down a slope.

摘要： When the output of a fuel cell starts to decrease, in consideration of the increase in the power generation efficiency, an instruction for the output of the fuel cell undergoes a smoothing process to gradually decrease the output, and excessive electric power generated during a period in which the power generation efficiency is high is used for charging a battery. While the output of the fuel cell is increasing, the power generation efficiency of the fuel cell is low. Thus, assisting electrical energy from the battery is increased. In this manner, the power generation output when the power generation efficiency of the fuel cell is low is reduced from a high power generation output to a low power generation output to achieve improvement in the average power generation efficiency.
