20140186735 | METHOD OF OPERATING FUEL CELL SYSTEM - A method of operating a fuel cell system includes calculating voltages that are generated in each cell of a stack. It is determined whether the voltages satisfy a voltage stability condition. When it is determined that the voltages satisfy the voltage stability condition, it is determined whether a moisture balance condition and a hydrogen supply condition are satisfied. When it is determined that the moisture balance condition and the hydrogen supply condition are satisfied, the voltage stability condition is relieved and reset. It is determined whether the voltages that are generated in each cell of the stack satisfy the reset voltage stability condition. When it is determined that the voltages that are generated in each cell of the stack satisfy the reset voltage stability condition, the stack is normally operated. | 07-03-2014 |
