    • A stable fuel supply system in a fuel cell system produces heat and electricity by combining hydrogen modified from a major raw material selected from various hydrogen compounds, with oxygen existing in air. A fuel supply device and a fuel supply method in a fuel cell system, which automate a steam to carbon ratio (S/C) control and a lamda control, and achieve a fuel cell system operation efficiently and stably coping with pressure loss and pulsation occurring within the system, while using a minimum number of balance-of-plant (BOP) units. A method more efficiently and precisely supplies fuel during the start-up and operation of the fuel cell system, while preventing flame failure of a burner and maintaining an appropriate carbon monoxide concentration even when an abrupt flow rate variation occurs. Also, an operating method improves functions associated with a decomposition ability based on selection of the specification of a fuel pump, and thus, is more economical and stable in terms of the costs and configuration of the fuel cell system.
    • 燃料电池系统中稳定的燃料供应系统通过将从各种氢化合物中选择的主要原料改性的氢与存在于空气中的氧组合而产生热和电。 燃料电池系统中的燃料供给装置和燃料供给方法,其使蒸汽/碳比(S / C)控制和拉姆达控制自动化,并且实现燃料电池系统运行,有效且稳定地应付压力损失和脉动发生 在系统内使用最少数量的植物平衡(BOP)单位。 在燃料电池系统的启动和运行期间,更有效和精确地提供燃料的方法,同时防止燃烧器的火焰故障,并且即使当突然的流量变化发生时也保持适当的一氧化碳浓度。 此外,根据燃料泵的规格的选择,操作方法改善与分解能力相关的功能,因此在燃料电池系统的成本和构造方面更加经济和稳定。
