Titanium Bipolar Plates – Engineered for High-Performance Fuel Cells & Electrolyzers

Created on 2025.12.29
Why OEMs Choose Titanium Bipolar Plates
Titanium bipolar plates deliver the optimalbalance of durability, lightweight design, and long-term performance,making them the preferred solution for next-generation PEM fuel cells andPEM electrolyzers.
Designed for demanding electrochemicalenvironments, titanium bipolar plates enable higher power density, longerstack life, and lower total cost of ownership (TCO) compared with stainlesssteel and graphite alternatives.
Key Advantages of Titanium BipolarPlates
Superior Corrosion Resistance for PEMEnvironments
Titanium offers exceptional resistanceto acidic and high-humidity conditions, forming a stable, self-healingoxide layer that prevents corrosion even under elevated operating voltages.
OEM benefits:
  • No metal ion contamination of membranes or catalysts
  • Stable performance over long operating cycles
  • Ideal for high-voltage PEM electrolyzers and automotive fuel cells
Lightweight & High Strength forCompact Stack Design
With a high strength-to-weight ratio,titanium enables ultra-thin bipolar plates without sacrificingmechanical integrity.
OEM benefits:
  • Reduced stack weight and volume
  • Higher power density per unit area
  • Optimized for automotive, aerospace, and portable systems
Low Contact Resistance with ProvenSurface Treatments
Titanium bipolar plates are fullycompatible with advanced conductive coatings such as TiN, carbon-basedcoatings, and noble metal layers, delivering low and stable interfacialcontact resistance (ICR).
OEM benefits:
  • High electrical efficiency
  • Long-term coating adhesion
  • Consistent performance over thousands of operating hours
Precision Manufacturing for AdvancedFlow Field Design
Titanium foils support precisionstamping, hydroforming, and laser welding, enabling complex micro-channelflow field patterns.
OEM benefits:
  • Improved gas distribution and water management
  • Reduced pressure drop
  • Enhanced fuel cell efficiency and durability
Excellent Thermal Management
Titanium bipolar plates provide efficientheat dissipation across thin structures, supporting uniform temperaturedistribution within the stack.
OEM benefits:
  • Stable high-current-density operation
  • Reduced thermal stress on membranes
  • Improved system reliability
Long Service Life & Lower Total Costof Ownership
Although titanium has a higher initialmaterial cost, its corrosion resistance, mechanical durability, and longlifespan significantly reduce replacement and maintenance costs.
OEM benefits:
  • Extended stack lifetime
  • Reduced downtime and service intervals
  • Lower lifecycle cost for commercial and industrial systems
