A successive approximation register analog-to-digital converter including separable dual capacitor array is disclosed. The disclosed successive approximation register analog-to-digital converter comprises: a dual capacitor array configured to include a first capacitor array for converting most significant bits of n bits and a second capacitor array for converting least significant bits of the n bits; a comparator configured to compare a level signal outputted from the first capacitor array with a level signal outputted from the second capacitor array; and an SAR logic circuit configured to convert an analog input voltage into a digital signal having the n bits by using the comparison result. Here, the first capacitor array includes a 1-1 capacitor circuit and a 1-2 capacitor circuit and the second capacitor array includes a 2-1 capacitor circuit and a 2-2 capacitor circuit. Each of the capacitor circuits includes capacitors connected in parallel each other.

A clamping device includes an oblique device and a unidirectional load control plate disposed on the outside of the fuel cell stack, not on the inside of the fuel cell stack. The device can automatically compensating the surface pressure in the fuel cell stack to be maintained constant, and provide a large clamping load with a small force using the load of the fuel cell stack.
