摘要： 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.

摘要： PROBLEM TO BE SOLVED: To discharge gas fuel collected in a tank storage space in an early stage. SOLUTION: Hydrogen leaking out of a hydrogen cylinder 18 has specific gravity smaller than that of air rises in a cylinder storage space and reaches a ventilation port 40 composed of slits formed at the upper surface of a roof cover 30. Since the ventilation port 40 is formed at a position corresponding to the upper side of the hydrogen cylinder 18, leaking hydrogen can reach the ventilation port 40 through a shorter distance as compared with the case that the ventilation port 40 is formed at a position shifted from the upper side of the hydrogen cylinder. Furthermore, the ventilation ports 40 are provided at a plurality of places, so that the leaking hydrogen reaches the closest ventilation port 40. After reaching the ventilation port 40, hydrogen gas upwardly passes through the ventilation port 40 to flow to the outside. COPYRIGHT: (C)2009,JPO&INPIT
