Abstract: The porous diffusion medium (DM) used in fuel cells has a complex heterogeneous structure in which both hydrophilic and hydrophobic pores coexist. The capillary flow in such a mixed-wet DM is mainly controlled by the capillary pressure and saturation relation (CPSR). In order to investigate the water transport characteristics in a passive DMFC, taking into account the coexistence of the hydrophilic and hydrophobic pores in the DM, we presented the mechanisms of capillary flow in the mixed-wet DM and provided a… Show more
