Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cell stacks, in particular to a hydrogen fuel cell stack and a detection system and method for the hydrogen fuel cell stack. Background technique [0002] Due to its high energy conversion efficiency and low impact on the environment, fuel cells have attracted great attention from research institutions and governments. In order to meet the power requirements, dozens or even hundreds of single cells are usually stacked in series to form a fuel cell stack. In the fuel cell stack, each single cell works relatively independently, and the output current is the same, but because the fuel cell stack is a series structure, the performance of a single cell will directly affect the performance output and use safety of the entire fuel cell stack sex. Therefore, as a part of the fuel cell detection system, single cell voltage detection is of great significance for the evaluation and analysis of fuel c...

Problems solved by technology

[0004] The traditional single-cell voltage detection system requires researchers to manually insert probes into each single cell, and the number of probes is fixed, which is only applicable to the corresponding number of stacks. For fuel cell stacks with different numbers of cells, new ones need to be remade. plate inspection terminal
