燃料电池系统及其控制方法
摘要：
本发明的燃料电池系统(100)的特征在于，具有：燃料电池(1)，其通过使供给至氧化剂极(34)的氧化剂气体与供给至燃料极(67)的燃料气体进行电化学反应来产生电力；燃料气体供给装置HS，其对上述燃料极(67)供给上述燃料气体；以及控制装置(40)，其控制上述燃料气体供给装置HS对上述燃料极(67)供给上述燃料气体，并且在上述燃料极(67)侧的出口被封闭时进行压力变动，该控制装置(40)基于以第一压力幅度ΔP1进行上述压力变动的第一压力变动模式，使上述燃料极(67)处的上述燃料气体的压力周期性地发生变动。
摘要（英）：

Provided is a fuel cell system (100) which is characterized by including: a fuel cell (1) which generates electric power by an electrochemical reaction between an oxidant gas supplied to an oxidant electrode (34) and a fuel gas supplied to a fuel electrode (67); a fuel gas supply device (HS) which supplies the fuel gas to the fuel electrode (67); and a control device (40) which controls the fuel gas supply device (HS) so as to supply the fuel gas to the fuel electrode (67) and changes the pressure when an exit of the fuel electrode (67) side is closed. The control device (40) cyclically changes the pressure of the fuel gas in the fuel electrode (67) according to a first pressure change pattern for executing the pressure change with a first pressure width [delta]P1.
