Slide 6: State-of-the-art continuous roll-to-roll coating line
State-of-the-art continuous roll-to-roll coating line • Continuous roll-to-roll coating for mass production of bipolar plates is an economic and environmentally sound solution. • By using readily available materials, and cutting process steps important cost reductions can be achieved. • Advanced coa
Slide 7: High performance coating
High performance coating Graphite like Carbon • Interfacial Contact Resistance below DOE target of 10 mΩ·cm2 at 140 N/cm2 – ICR equal to gold at contact pressure > 100 N/cm2 • Increase in ICR of < 2 Ω·cm2 after biaxial straining* of 30% and potentiostatic testing in simulated fuel cell environment *
Slide 8: High-velocity formed patterns
High-velocity formed patterns 34 % Examples of formed patterns with Sanergy LT 316L. 38 % Channel forming elongation increasing from 34 to 52%. The 45 % channel pitch varies between 0.9 mm to 1.6 mm. 50 % 52 %
Slide 9: Why enhanced formability?
Why enhanced formability? Stress Material properties are dependent on speed. Ultimate Tension 316L UTS 103 Rupture Tensile Stress is increasing that results in enhanced formability. Ultimate Eq. Stress UTS 100 UTS 10-3 High Velocity Conventional Elastic Strain rate region -1 J Phys IV France 7 “Dyna
Slide 10: The stamping and forming process
The stamping and forming process Just before forming starts Partly formed Forming just completed V≤20 m/s V≤15 m/s V= 0 m/s A process similar to conventional stamping. The main difference is the forming velocity or speed.
Slide 11: Why a 2-step forming process?
Why a 2-step forming process? Limited stretching of material from landing 1-step Necking in area of radii A copy of the protrusion of the tool. 2-step More uniform cross-section, particularly at landings. No necking.
Slide 12: Why a 2-step forming process?
Why a 2-step forming process? 1-step forming No necking is obvious for tougher patterns. A 2-step process enables tough 2-step forming patterns with a channel forming elongation of 50+ % to be formed.
Slide 13: Production line for high-volume production
Production line for high-volume production • Similar forming technology, forming plates from thin sheet metal coil. • Many lines in operation world wide, proven technology • Fully automated high-volume production
Slide 14: Line concept for high volume production
Line concept for high volume production PVD Coating Pre-form High-speed Cutting and and pre-cut forming handling
