Mechanical fatigue durability of catalyst coated membranes (CCMs) is measured.
•
A finite element based fatigue model is developed for the CCM material.
•
The maximum tolerable stress of CCM is found to be lower than that of pure membrane.
•
Temperature cycling is found to be more severe than humidity cycling.
•
Combined temperature and humidity cycling can significantly reduce fatigue lifetime.
