Abstract:
      The poor water management of a proton exchange membrane fuel cell(PEMFC) will increase its internal resistance and hinder the oxygen reduction reaction. Therefore, effective water management is one of the key strategies to improve its performance and durability. It is also worth noting that the phenomena including membrane dehydration, catalyst layer overflow, mass transfer and fluid flow state will be affected by the distribution and movement of water in the passage. In this paper, the related literature on the key technologies of PEMFC water management is reviewed, and various technical solutions to the improvement of water management are discussed. Moreover, the research results of the formation and diffusion of liquid droplets and their interaction with gas diffusion layer(GDL), which are studied using tec-hniques such as neutron imaging and electron microscopy, are summarized. The simulations of the movement of water dro-plets and slug formation in fuel cell micro-channels using the CFD model and VOF method are also analyzed in detail.
