Abstract
A system for testing durability of a gas diffusion layer (GDL) is provided, including a clamping component, a liquid storage tank and a peristaltic pump. The clamping component is configured to fix the GDL. The liquid storage tank is configured to store a corrosive liquid. The peristaltic pump is arranged between the clamping component and the liquid storage tank. The peristaltic pump is connected to the clamping component via a first pipeline, and is connected to the liquid storage tank via a second pipeline. A GDL durability testing method is also provided. During the testing, the corrosive liquid is pumped into the clamping component to perform erosion-corrosion on the GDL.
