摘要： In a fuel cell system, when an electric current drawn from fuel cells is controlled based on a target power generation value, an upper limit of the electric current is optimally set to make suspensions of operation caused by voltage drops to be as infrequent as possible. The upper limit of the electric current is set by adding a predetermined offset value (e.g., 2 A) to an average value of the electric current before a predetermined delay time (e.g., 10 seconds). Moreover, when the electric current drawn from the fuel cells is controlled based on a target power generation value, the value of the electric current is compared with the upper limit of the electric current, to control the electric current.

摘要： This fuel cell system monitors the temperature of an off-gas combusting unit detected by a combustor temperature detecting unit in a constant output operation state such as a rated operation state where a sweeping current of a cell stack becomes constant, rather than directly measuring the fuel property, and controls the flow rate of the cathode gas so that the temperature of the off-gas combusting unit reaches a target temperature. Moreover, the fuel cell system determines the fuel property based on the variation of the flow rate of the cathode gas changed until the temperature of the off-gas combusting unit reaches the target temperature and the temperature of the cathode gas. Thus, it is possible to simplify the configuration required for determining whether the fuel property has changed or not as compared to a conventional method of measuring a plurality of factors of the fuel property.
摘要翻译：该燃料电池系统以恒定的输出运行状态监视由燃烧器温度检测部检测出的废气燃烧部的温度，例如电池堆的扫掠电流恒定的额定运行状态，而不是直接测量燃料性能，并控制阴极气体的流量，使得废气燃烧单元的温度达到目标温度。此外，燃料电池系统基于改变的阴极气体的流量的变化来确定燃料特性，直到废气燃烧单元的温度达到目标温度和阴极气体的温度。因此，与传统的测量燃料特性因素的方法相比，可以简化确定燃料特性是否变化所需的结构。
