The invention relates to a fuel cell pile online regional detection system and a fuel cell pile online regional detection method. The detection system comprises piles, PCBs, a data acquisition device and a computer; the PCBs are arranged in the piles; the input end of the data acquisition device is connected with the PCBs; and the output end of the data acquisition device is connected with the computer. The detection method comprises the following steps that: a plurality of PCBs are adopted to replace single-body anode boards, and sealing is performed; hydrogen, air and water are led into the piles, so that the piles can work normally; after the piles can work normally, regional current density signals, temperature signals and single-body voltage signals measured by the PCBs are acquired by the data acquisition system, and data processing results are transmitted to the computer; and the computer converts received data into a two-dimensional distribution graph and displays the graph, and therefore, regional properties of the piles can be detected in an online manner. Compared with the prior art, the fuel cell pile online regional detection system and method of the invention are advantageous in basic avoidance of pile structure modification, a large number of detected performance parameters, intuitive display of measurement results, wide application and the like.
Description
technical field [0001] The invention relates to a performance detection system and method in the field of fuel cells, in particular to an online partition detection system and detection method for fuel cell stacks. Background technique [0002] Fuel cells (PEMFC) are regarded as the best substitute for internal combustion engines due to their high power density, environmental friendliness, and rapid start-up, and have received great attention from governments and automobile manufacturers. However, the life and stability of the fuel cell stack is still a big problem, and its performance is affected by many factors, such as temperature, humidity, flow field shape and so on. The influence of these factors is directly reflected in the distribution of current density and temperature inside the fuel cell. Therefore, it is of great significance to the research of fuel cells to use the PCB board to detect the fuel cell partition performance to detect the current density, temperatur...
