Welding Technologies for Metallic Bipolar Plates in Proton Exchange Membrane Fuel Cells: A Critical Review of Processes, Joint Performance, and Manufacturing Readiness
Yueyang Liu · Journal of Engineering Research and Reports · 2026
Metallic bipolar plates (BPPs) enable thin, lightweight, and high-throughput proton exchange membrane fuel cell (PEMFC) stacks, but their industrial value depends on joining two formed foils without sacrificing gas tightness, dimensional accuracy, electrical performance, or corro...
