The invention provides a control method for a fuel cell system having a fuel cell of the solid oxide type, which receives supplies of an anode gas and a cathode gas to generate power. The control method for the fuel cell system includes an anode protection implementation determining process for determining whether to implement an anode protection process by applying a predetermined protection current to the fuel cell so as to suppress catalyst oxidation in the anode of the fuel cell. The anode protection implementation determining process acquires the fuel cell internal impedance for an anoderesponse frequency at which the fuel cell anode reaction resistance may be detected, and determines, on the basis of the internal impedance at the anode response frequency, whether or not to implementthe anode protection process. 提供一种燃料电池系统的控制方法，该燃料电池系统具有接受阳极气体和阴极气体的供给来进行发电的固体氧化物型的燃料电池，该燃料电池系统的控制方法包括进行阳极保护处理的实施判断的阳极保护实施判断处理，该阳极保护处理是对燃料电池施加规定的保护电流以抑制燃料电池的阳极的催化剂氧化的处理，在阳极保护实施判断处理中，获取在能够探测出燃料电池的阳极反应电阻的阳极感应频率下的燃料电池的内部阻抗，基于阳极感应
