Beschreibung
Zusammenfassung:	The invention discloses a control method of a fuel cell tail gas recovery power generation device with a bypass valve, which is characterized in that the bypass valve is arranged at a gas inlet of the power generation device, and the opening degree of the bypass valve is controlled according to the wake flow of a fuel cell, so that the problem that the flow is too large is avoided; the impeller and the thrust bearing are damaged when the flow is larger than the flow borne by the power generation device. 本发明公开一种具旁通阀的燃料电池尾气回收发电装置的控制方法，其在发电装置的进气口处提供旁通阀，并根据燃料电池的尾流流量控制旁通阀的开度，进而避免因流量过大，在大于发电装置所能承受流量时造成叶轮和推力轴承的损坏。
