摘要:
The present invention provides a method for supplying fuel to a fuel cell, which comprises steps of: (a) feeding a specific amount of a fuel into a fuel cell system; (b) determining a specific monitoring period according to a characteristic value measured from the fuel cell when subjected to a load; (c) detecting if the load is varying during the specific monitoring period ; and (d) selecting to proceed to the step (a) or (b) according the variation of the load. In one embodiment, the method further comprises a step (e) determining, if the load is not changed, whether the specific amount of fuel is enough to judge the timing for supplying the fuel. By the aforesaid method, the supplying of fuel to the fuel cell under dynamic load can be effectively controlled for optimizing the performance of the fuel cell without the use of fuel concentration sensor.

The present invention provides a fuel sensor-less control method for supplying fuel to a fuel cell, in which a fixed control amount is determined for controlling the fuel supply of fuel cell, and then a feeding timing of the fixed fuel quantity is determined by integrating characteristic values generated from the fuel cell within the limit of fixed control amount. In another embodiment, it is further comprising a step of determining the variation profile associated with the characteristic values during the period so as to judge whether it is necessary to feed the fuel into the fuel cell or not. By means of the present invention, the supplying of fuel to the fuel cell under dynamic loadings can be effectively controlled for optimizing the performance of the fuel cell as well as reducing the cost without installing any fuel concentration sensor.

The present invention provides a method and system for image identification and identification result output, wherein a feature image under identification acquired from an image is compared with a plurality of sample images respectively stored in a database so as to obtain a plurality of similarity indexes associated with the plurality of sample images respectively. Each similarity index represents similarity between the feature image and the corresponding sample image. Thereafter, the plurality of similarity indexes are sorted and then a least one of comparison results is output. The present invention is further capable of being used for identifying identification marks with respect to a carrier. By sorting the similarity index with respect to each feature forming the identification marks, it is capable of outputting many sets of combinations corresponding to the identification marks so as to improve speed for targetting suspected carrier and enhance the identification efficiency.
