Abstract
This study is motivated by the need to develop a validated capillary pressure-saturation relationship that can precisely describe the capillary transport characteristics of the fuel cell diffusion media (DM). A series of capillary pressure-saturation measurements were performed for SGL 24 series DMs tailored with various degrees of PTFE loadings (from 5% to 20% of wt.) over a wide range of operating conditions (i.e. at different temperatures and compressions). The benchmark data were then utilized to deduce an appropriate form of Leverett approach that can precisely determine the capillary pressure of the tested fuel cell DMs as a function of hydrophobic additive content, operating temperature, liquid saturation, compression pressure and uncompressed porosity of the DM.
