Abstract

The invention discloses a fuel cell hydrogen cycle test system. A hydrogen gas source is connected with the inlet pipeline of a heat exchanger, the outlet of the heat exchanger is connected with the hydrogen inlet pipeline of a hydrogen cycle device, and the hydrogen outlet of the hydrogen cycle device is connected with the inlet pipeline of a heating and humidifying device; the first outlet of the heating and humidifying device is connected with an emptying pipeline, and the second outlet of the heating and humidifying device is connected with the reflux inlet of the hydrogen circulating device through a reflux pipeline; the heat exchanger adjusts the temperature of hydrogen supplied by the hydrogen source; the heating and humidifying device heats, humidifies and discharges the hydrogen; and the hydrogen circulating device sucks and reflows the hydrogen and supplies the hydrogen to the heating and humidifying device again. The heating and humidifying device is adopted to replace a galvanic pile, the actual consumption flow, pressure, temperature and humidity of the galvanic pile are completely simulated, heat exchange and humidifying are carried out on hydrogen, it is guaranteed that discharged hydrogen reaches a saturated state, and through suction backflow of the hydrogen circulating device, the characteristics of a fuel cell hydrogen circulating system are completely simulated and analyzed.

Description

technical field [0001] The invention belongs to the field of fuel cells, in particular to a fuel cell hydrogen cycle test system. Background technique [0002] With the update and practical application of fuel cell technology, in order to adapt to the new fuel cell technology and vehicle environment, the performance and structure of the fuel cell hydrogen circulation system will also change. In order to understand the change in its performance, it is necessary to develop a set of fuel cell The hydrogen cycle test system is used to analyze the performance of the hydrogen cycle system of the fuel cell in more detail and further improve the design of its structure. [0003] The existing fuel cell hydrogen circulation test system is basically connected. After the dry hydrogen is humidified through the heat exchange of a separate heater and humidifier, it is discharged through the buffer tank of the simulated stack cavity, and is discharged by the hydrogen circulation pump. It i...
