    • A fuel supplying and controlling method and a fuel cell apparatus are provided in the present invention, in which a fuel sensor-less control method and a fuel concentration sensor are combined together to stabilize the operation of the fuel cell apparatus. In one embodiment of the present invention, an optimum range of fuel concentration is determined using the fuel sensor-less control method and then whether the fuel cell apparatus operates within the optimum range of fuel concentration or not is monitored using the fuel concentration sensor as a first line of defense, while the fuel sensor-less control method is used as a secondary line of defense for monitoring. In another embodiment of the present invention, the fuel sensor-less control method is used as a first line of defense for monitoring whether the fuel cell apparatus operates within the optimum range of fuel concentration or not and determining an optimum range of fuel concentration, while whether the fuel concentration exceeds the optimum range of fuel concentration is monitored using the fuel concentration sensor as a second line of defense for monitoring the fuel concentration.
    • 在本发明中提供了一种燃料供给和控制方法以及燃料电池装置,其中将无燃料传感器控制方法和燃料浓度传感器组合在一起以稳定燃料电池装置的操作。 在本发明的一个实施例中,使用燃料无传感器控制方法确定燃料浓度的最佳范围,然后使用燃料浓度传感器作为燃料浓度传感器来监视燃料电池装置在最佳燃料浓度范围内的运行方式 第一道防线,而无燃料传感器的控制方式被用作二级防御用于监控。 在本发明的另一个实施例中,燃料传感器控制方法被用作第一防线,用于监测燃料电池装置在最佳燃料浓度范围内是否运行,并且确定燃料浓度的最佳范围,同时 使用燃料浓度传感器作为监测燃料浓度的第二防线来监测燃料浓度是否超过燃料浓度的最佳范围。
