质子交换膜燃料电池钛双极板研究进展OA北大核心CSTPCD

The bipolar plate is a crucial component of the proton exchange membrane fuel cell(PEMFC),with their performance playing a key role in the structural stability,long-term durability,efficiency,and power density.Metal bipolar plates have attracted much attention due to their low cost,outstanding mechanical properties,and effective electrical and thermal conductivity.Among these materials,titanium possesses low density,excellent airtightness,high tensile strength,and exceptional corrosion resistance in acidic environments,which makes them highly promising for use in PEMFCs.However,the corrosion resistance,electrical conductivity,hydrophobicity,and heat and mass transfer properties of titanium bipolar plates are significantly influenced by the coating materials and forming methods.Therefore,this paper first introduce the functions and requirements of bipolar plates in PEMFC.It then reviews the main research findings from recent years regarding the coating materials and forming methods of titanium bipolar plates,and concludes with a discussion of future research directions.
