Abstract

The invention provides a fuel cell voltage inspection device, and relates to the technical field of fuel cells. The fuel cell voltage inspection device comprises a mounting bracket and a plurality of inspection mechanisms arranged at the bottom of the mounting bracket; the inspection mechanism comprises a PCB, a mounting base and a W-shaped elastic sheet; a plurality of mounting sliding grooves are formed in the bottom of the mounting base; correspondingly, a plurality of avoiding holes are formed in the top of the mounting base; the receding holes communicate with the mounting sliding grooves correspondingly. The PCB is arranged at the top of the mounting base; a plurality of copper sheets are arranged on the lower surface of the PCB; a first connecting part is arranged in the middle of the W-shaped elastic sheet, and second connecting parts are respectively arranged at two ends; the W-shaped elastic sheet is clamped in the mounting sliding groove and the avoiding hole, so that the first connecting part and the second connecting part are respectively propped against the copper sheet and a single battery in the electric pile, and further, the copper sheet is electrically connected with the single battery. According to the invention, the fuel cell voltage inspection device is good in reliability and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell voltage inspection device. Background technique [0002] Fuel cells are generally composed of hundreds of single cells. When the voltage of any single cell fluctuates within a certain range, it will affect the normal operation of the entire system, and even damage the stack in severe cases. Therefore, when the fuel cell is working, it is necessary to detect the voltage of a single cell at all times. When it is found that the voltage of a single cell exceeds the safe voltage range, the control strategy of the whole machine responds according to the fluctuation of the voltage to ensure the normal operation of the system. Protect the stack. [0003] At present, the structures of common voltage inspection devices are pin-type or adhesive-type. The pin-type voltage inspection device needs to open a special-shaped process slot on the bipolar plate, which not only incre...
