“…In this study, the humidification system was applied to the humidification of a 100‐kW stack module, in which the number of stacks was 380. The single‐cell performance of a stack was derived from experimental tests 39 . The test stack used is shown in Figure 4A with 100 cells, an active cell area of 400 cm 2 , and the output power of the stack of 26.4 kW.…”

Summary Maintaining proper membrane humidity is essential for ensuring the optimal operation and durability of polymer electrolyte membrane fuel cells (also known as proton exchange membrane fuel cells). Conventional humidification systems have insufficient humidification capacities and slow humidity responses, and they can no longer meet the humidification needs of high‐power fuel cell systems. This study focuses on a high‐power fuel cell air humidification system. The humidification system uses a mixture of dry and wet air to enable rapid achievement of the inlet gas humidification requirements of the fuel cell. A complete model of the air humidification system is developed, and a proportional‐integral‐derivative controller is used to provide feedback control of the temperature and humidity in the humidification system. The results show that the overall relative humidity (RH) output of the humidification system exhibits high‐accuracy tracking of the RH demand under different operating conditions, without large oscillations. Meanwhile, the temperature of the mixing heater remains consistent with the temperature of the fuel cell stack. The trend for the wet air flow rate is basically identical to the change in the RH, and the change in the heating power of the mixer heater is almost the same as the change in the dry air flow rate. In addition, under the same humidification demand, the humidity regulation of this system at different operating powers has a better anti‐interference ability, and the maximum RH deviation is 8%. The results of the study can provide guidance for the optimal operation of existing high‐power fuel cell humidification systems.

With the growing concerns over the energy crisis and environmental pollution, fuel cells have attracted increasing attention. Proton exchange membrane fuel cells (PEMFCs) have promising prospects due to their economic efficiency, low noise, and minimal environmental pollution. However, the existing commercial testing systems for PEMFCs suffer from limited functionalities and lack of scalability. In this study, we propose the design of a testing platform specifically tailored for water-cooled PEMFCs with a power greater than 1 kW. The functionality of the testing platform is verified through static and dynamic testing, demonstrating its compliance with the required standards. Furthermore, a fault diagnosis model for fuel cell stacks is developed based on the back-propagation (BP) neural network, achieving an overall accuracy rate of over 95% for fault classification.
