摘要： PROBLEM TO BE SOLVED: To stop a fuel cell system with its startup time reduced and without using up power of a secondary battery in case a fuel cell is incapable of activation.
SOLUTION: In case an ignition key is switched on, a control part 6 calculates possible standby time capable of waiting the fuel cell 2 to start up based on power charged to a secondary battery 52. While passing through the standby time after the ignition key is switched on, in case the fuel cell 2 does not start up, the control part 6 lights up an alarm lamp for informing startup incapability of the fuel cell 2. On the other hand, in case the fuel cell 2 starts up, a regular operation for activating a traction motor 54 or the like is started with the use of power generated by the fuel cell 2 and power discharged to the secondary battery 52.

摘要： PROBLEM TO BE SOLVED: To provide a technology to suppress deterioration of a fuel cell.
SOLUTION: In a fuel cell system 100, when a significant voltage reduction in at least one part of a single cell 1 of a fuel cell stack 10 is detected, voltage recovery treatment is carried out so that its power generation capacity is recovered. In the voltage recovery treatment, by a control part 40, a stack of the fuel cell stack 10 is measured, and based on this measurement value, wet state of electrolyte membrane in the interior of the fuel cell is measured. When the control part 40 determines that the wettability is low in the measurement of the wettability, current limiting treatment which temporarily limits output of the fuel cell stack 10 in order to recover the electric generation capacity, is started in a more moderate condition than when it determines the wettability is high.

摘要： PROBLEM TO BE SOLVED: To carry out a suitable power generation control during a high potential avoiding operation. SOLUTION: A fuel cell system is equipped with a fuel cell to generate power by receiving supply of a reaction gas, and a controller to carry out high potential avoiding control of an output voltage of the fuel cell by making a high potential avoidance voltage lower than its open end voltage as the upper limit. The controller calculates the larger system demanding power of a system demanding power P A calculated from a load demand and a system demanding power P B calculated from the high potential avoidance voltage as the system demanding power for the fuel cell. In order to calculate the system demanding power for the fuel cell, since not only the system demanding power P A calculated from the load demand but also the system demanding power P B calculated from the high potential avoidance voltage is taken into account, stable power generation can be carried out without fuel shortage. Moreover, since power generation amount can be controlled appropriately, overcharge of the battery can be prevented. COPYRIGHT: (C)2009,JPO&INPIT
