Abstract:Cold
start is a challenge for the proton exchange membrane fuel
cell, and understanding the heat transfer characteristics of solid–liquid
phase change in this process is necessary. An enthalpy-based lattice
Boltzmann model is established, and the heat transfer of ice melting
in in-plane and through-plane of the gas diffusion layer (GDL) is
studied. The effects of fiber diameter, double heat sources, and Rayleigh
number are analyzed. It is found that the fiber diameter has a significant
influence on heat transf… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
