Abstract
(EN) The present invention provides a Fuel cell system, which comprises a plurality of fuel cells connected to one another in series, and a reformer for reforming raw fuel. The reformed fuel from the reformer is supplied to a first stage of the plurality of fuel cells. The fuel cells in the first stage are equipped with a methane reaction suppression function whereby the reaction of the methane contained in the reformed fuel is more suppressed than at least one of the fuel cells in a second or further stage. In the fuel cell system where the plurality of fuel cells are disposed in series, power-generation efficiency can be improved by limiting a decrease in temperature caused by an endothermic reaction in a fuel cell of the first stage.
(ZH) 本发明提供一种燃料电池系统，其中，该燃料电池系统包括：多个燃料电池，该多个燃料电池互相串联连接起来；以及重整器，其用于对原燃料进行重整，经重整器重整后的重整燃料被供给至多个燃料电池的第一级的燃料电池，与第二级及其后的至少一个燃料电池相比，第一级的燃料电池具有抑制在重整燃料中包含的甲烷的反应的甲烷反应抑制功能。通过抑制第一级的燃料电池的因吸热反应而产生的温度降低，能够提高将多个燃料电池串联配置而成的燃料电池系统的发电效率。
