| 摘要 |
An object of the invention is a control arrangement, which comprises means (120) as a first control mechanism for determining assumed inlet fuel composition information, means (122) for determining predicted cell voltage information, and means (124) for determining a correction term to the assumed inlet fuel composition information based on the difference between said measured cell voltage information and said predicted cell voltage information. The control arrangement comprises at least one superposed control mechanism (126, 128) to the first control mechanism for performing at least mainly tuning type control operations, which have a distinct time constant between control operations compared to the control operations of the first control mechanism, said tuning type control operations being performed for matching the assumed inlet fuel composition information to the real fuel composition during start-up or operation of the fuel cell system. |
