Abstract
In polymer electrolyte membrane fuel cell (PEMFC), the cost and durability are main challenges to commercialization. To achieve the long-term durability target, the durability of PEMFC materials should be further improved. In this paper, we investigated the chemical and electrochemical degradation of the expanded polytetrafluoroethylene (e-PTFE) support and examined how it influences the mechanical properties of the e-PTFE support. We conducted the Fenton test and open circuit voltage (OCV) holding and analyzed the chemical and physical structural changes of the e-PTFE support by utilizing Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), and tensile test. After the chemical and electrochemical degradations, the molecular bonds of e-PTFE were broken, and the microstructures of e-PTFE were deformed. As the result the mechanical properties of e-PTFE showed significant decrease. Consequently, our results show that the e-PTFE support is deteriorated chemically during PEMFC operation, and this chemical degradation lead reduction of mechanical strength.
