摘要：

During operation of Polymer Electrolyte Membrane Fuel Cells (PEMFCs), electro-chemical reactions generate water, which exists as a liquid because of the PEFMC's low operating temperature. The water remains in the PEFMC after it is turned off. During the winter this water can freeze; associated increase in its volume deforms the gas diffusion layer (GDL). The deformed GDL reduces the cell's power output and durability. In this investigation, X-ray microscopy was used demonstrate that water freezing changed the geometry of GDL by water freezing
