Title:
燃料電池システムおよびその制御方法
Document Type and Number:
Japanese Patent JP5800279
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress power consumption in a cell monitor while avoiding a considerable drop of a cell voltage.SOLUTION: In an intermittent operation in which, during a low load of a fuel cell, the fuel cell is temporarily suspended, a cell monitor for measuring a cell voltage of the fuel cell is stopped. When the cell monitor is activated after the intermittent operation is terminated, the output of the fuel cell is limited. A predetermined threshold value is set as a post-intermittent termination threshold value. The intermittent operation is preferably terminated when a system requiring power indicating an output that the fuel cell system requires the fuel cell exceeds the post-intermittent termination threshold value. A cell monitor activation threshold value that is a threshold value for instructing activation of the cell monitor is preferably changed to a smaller value than the post-intermittent termination threshold value, after the intermittent operation is terminated.
