Title:
POWER GENERATION MONITORING DEVICE, FUEL BATTERY SYSTEM AND POWER GENERATION MONITORING METHOD
Document Type and Number:
Japanese Patent JP2016085898
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To detect occurrence of negative voltage in a method for monitoring status of power generation on the basis of voltage for a plurality of cells.SOLUTION: If possibility of generation of negative voltage is detected on the basis of a voltage measured for each cell, the flow rate of oxygen is increased (Step S710). If the measured voltage reaches a second voltage V2 or higher thereafter (step S720, YES), it is determined that oxygen shortage, leading to negative voltage, has been occurring. (step S750). Conversely, if the measured voltage does not reach the second voltage V2 or higher (Step S730, YES or step 740, YES), it is determined that air shortages has been occurring (step S770).SELECTED DRAWING: Figure 6
