Description

technical field [0001] The invention relates to the field of fuel cell structure design, in particular to an FPC flexible wiring harness connecting plate structure for inspection of fuel cell stacks. Background technique [0002] The core of a high-power fuel cell stack is often assembled by hundreds of single cells. In order to detect the voltage of each cell, the stack is connected to detect the battery voltage through a low-voltage wiring harness. However, the number of high-power fuel cell stacks is large, dozens or even hundreds of nodes. If traditional low-voltage wiring harnesses, such as Teflon, are used to connect the wiring harnesses, the number of wiring harnesses will be as many as hundreds, which will easily increase the overall mass of the stack. Reducing the mass power density of the fuel cell reduces; too many wire harnesses will also take up a large space, resulting in a decrease in the volume power density of the fuel cell, and at the same time too many wir...
