Titanium Bipolar Plates
Bipolar plates form the structural and electrical backbone of fuel cell and electrolyzer stacks. They enable uniform reactant distribution, efficient current collection, and thermal management while providing mechanical stability to the stack assembly. Material selection, flow field design, and surface treatment directly influence efficiency, durability, and long-term system performance.
AEM Membrane
Anion Exchange Membranes (AEMs) are critical to AEM water electrolyzers, enabling efficient hydroxide ion transport while maintaining mechanical and chemical stability. Membrane performance directly influences system efficiency, cost optimization, and operational durability in green hydrogen production systems.
Gas Diffusion Layer
Gas Diffusion Layers (GDLs) facilitate uniform gas transport and effective water management within PEM fuel cells and hydrogen systems. Their porous structure supports electrical conductivity while maintaining mechanical integrity under compression. Proper GDL selection plays a critical role in stack stability and electrochemical performance.
Titanium PTL
Porous Transport Layers (PTLs) are positioned between the catalyst layer and bipolar plate in electrolyzers. They enable uniform water distribution and gas removal while supporting the catalyst structure under high current density operation. Material grade, porosity, and surface treatment significantly affect electrochemical efficiency and durability.
