Uniform Load Assembly Method of PEMFC Under Vibration Based on the Wave Spring Suspension Support
摘要
Proton exchange membrane fuel cell (PEMFC) as an efficient energy device, has great application prospects. However, due to the assembly design, the efficiency and reliability of PEMFC are easily affected, especially the uneven distribution of bipolar plate contact pressure. Therefore, a simple and reliable assembly methodology based on the wave spring is proposed to achieve the purpose of uniform load and obtain high-performance PEMFC in this paper. The effectiveness of wave spring suspension approach is verified by experiments. This achievement represents an important step in improving the performance of PEMFC.
