摘要：

Over the past few years, the importance of water management to the successful operation of polymer electrolyte membrane (PEM) fuel cells has stimulated an extensive research focus on liquid water transport and its effect on performance and durability. Empirical methods employed to investigate water transport in the fuel cell have the potential to provide useful feedback for developing empirical correlations and validating numerical models for fuel cell research and development. In this paper, a literature review is provided for the experimental techniques that have been applied to visualize liquid water in operating hydrogen PEM fuel cells and flow fields. The main hypotheses that have been proposed to describe liquid water transport in the gas diffusion layer (GDL) and current challenges will also be discussed.
