Fuel-Cell Bipolar Plates places specific demands on the alloys that serve it. Jiangsu DZX Alloy supplies Stainless steel, Titanium & titanium alloys for this duty, combining 24+ years of precision-alloy manufacturing experience with an ISO9001 triple-inspection system, a 12,000 m2 self-owned factory and full batch traceability. Within New Energy Applications, fuel-cell bipolar plates combines these requirements in its own way.
The hydrogen and battery economy runs on precisely processed metals: fuel-cell bipolar plates, titanium and nickel components for PEM electrolysers, nickel current collectors for solid-state and lithium cells, nickel foam electrodes, thermocouples for storage temperature monitoring and FeCrAl/NiCr heating elements for thermal management. Jiangsu DZX Alloy supplies these material families under one quality system, from prototype quantities to volume production.
General Requirements for Fuel-Cell Bipolar Plates
- Corrosion resistance in electrolyte and hydrogen environments.
- Dimensional precision: plate thickness, mesh geometry and pad accuracy held batch to batch.
- Electrical performance: controlled resistivity and conductivity for collectors and busbars.
- Surface condition: clean, coating-ready surfaces for catalysis and welding.
- Supply-form fit: materials must be available in the forms fabrication requires — typically plate0.5-100mm, strip, tube OD3-300mm / wire0.1-6mm, strip, plate, bar, tube.
Recommended Materials & Specifications for Fuel-Cell Bipolar Plates
The following grades and specifications apply to this application; all values are as supplied by Jiangsu DZX Alloy with per-batch certificates:
| Material | Representative grades | Key properties | Available forms |
|---|---|---|---|
| Stainless steel | 304, 316, 316L | 316L: Cr 16-18%, Ni 10-14%, Mo 2-3% | wire0.1-6mm, strip, plate, bar, tube |
| Titanium & titanium alloys | TA1, TA2, GR1, GR2, GR5 | density 4.4-4.5 g/cm³; tensile strength 600-1200 MPa | plate0.5-100mm, strip, tube OD3-300mm |
Stainless steel (304, 316, 316L) is specified for its 316L: Cr 16-18%, Ni 10-14%, Mo 2-3%. Jiangsu DZX Alloy supplies it as wire0.1-6mm, strip, plate, bar, tube, with dimensions produced to drawing; supported fabrication routes include bending, welding, stamping and machining as the form allows. Titanium & titanium alloys (TA1, TA2, GR1, GR2, GR5) is specified for its density 4.4-4.5 g/cm³; tensile strength 600-1200 MPa. Jiangsu DZX Alloy supplies it as plate0.5-100mm, strip, tube OD3-300mm, with dimensions produced to drawing; supported fabrication routes include bending, welding, stamping and machining as the form allows.
Available supply forms by grade:
- Stainless steel: wire0.1-6mm, strip, plate, bar, tube
- Titanium & titanium alloys: plate0.5-100mm, strip, tube OD3-300mm
Customisation: Grades, diameters, wall thicknesses and lengths can be manufactured to customer drawings, and samples are available on request. thin-gauge plate/strip,strict thickness tolerance,surface finish suitable for coating processes.
Application Scenario Deep Dive: Fuel-Cell Bipolar Plates
Scaling from prototype to volume is where material variation bites: tolerances that were acceptable on a 50 kW stack become yield problems at 1 MW. Jiangsu DZX Alloy’s approach is to fix the measurable parameters — thickness, porosity, resistance, surface — with per-batch verification and uniform-format reports, so stack designs can be frozen on sample-lot evidence instead of volume-lot hope.
When 316L: Cr 16-18%, Ni 10-14%, Mo 2-3% governs the duty, Stainless steel is the typical first call; Titanium & titanium alloys is preferred where density 4.4-4.5 g/cm³; tensile strength 600-1200 MPa matters more. Jiangsu DZX Alloy’s engineering team can review your duty conditions and confirm the grade, condition and tolerance before ordering.
Fuel-Cell Bipolar Plates does not operate in isolation: within New Energy Applications it sits alongside PEM Electrolyser Components, Solid-State & Lithium Battery Current Collectors, Flow-Battery Electrodes & Nickel Foam, and material choices made here often share grades, documentation and inspection practice with those duties. Reviewing the neighbouring application pages is the fastest way to see where specification boundaries lie.
