Abstract

The invention relates to a fuel cell cold starting partition performance test system and test method. The test system comprises a fuel cell, an oxidizing agent supply unit, a fuel supply unit, a clamping unit, a humidification unit, a cooling pipe, a high-low temperature box, a partition test plate, a load unit, a data acquisition unit and a data processing unit. The test method comprises the following steps: the anode plate of the fuel cell is replaced with the partition test plate; the temperature in the high-low temperature box reaches a set low-temperature environment temperature; oxidizing agent and fuel are provided for the fuel cell to make the fuel cell be in normal operation; the data acquisition unit is used to acquire the voltage drop across two ends of each embedded resistor, the voltage of each temperature resistor and the current flowing through the temperature resistor on a real-time basis; and the data processing unit is used to calculate the current density distribution of each partitioned region in the fuel cell and the partition temperature at each moment according to received signals to obtain a current density distribution diagram and a temperature distribution diagram. Compared with the prior art, the test system and test method of the invention have advantages of convenient operation, visual measurement and high stability.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to a fuel cell cold start zone performance test system and a test method. Background technique [0002] With the shortage of traditional energy sources such as fossils and the continuous warming of the global climate, human beings are facing a huge energy crisis and survival crisis. It is urgent to seek new, efficient and clean energy to gradually replace traditional energy to deal with the energy crisis. Due to its excellent performance, fuel cells have become a research hotspot in various countries in the world, and have played a huge role in power generation, mobile power supply, and vehicle power supply. The research on fuel cell vehicles is getting deeper and deeper, but there are still technical bottlenecks in its commercialization. In addition to battery durability and cost factors, improving low-temperature start-up performance is also one of the key issues. [0003] When the loc...
