An ultrathin layer of hydrophilic titanium dioxide (TiO2) is coated on the gas diffusion layer (GDL) to enhance the performance of a proton exchange membrane fuel cell (PEMFC) at low relative humidity (RH) and high cell temperature. Both of the modified and unmodified GDLs are characterized using contact angles, and the cell performance is evaluated at various RHs and cell temperatures. It is found that the modified GDL, which contains a hydrophilic TiO2 layer between the microporous layer (MPL) and the gas diffusion-backing layer (GDBL), exhib...
