Revolutionizing PEMWE Cost at Scale:

Hydrogen Contango has dedicated years of R&D efforts to achieving a breakthrough in PEMWE cost competitiveness. Our latest HCCT (H2 Crossover Control Technology) enables ultra-thin PEM designs, unlocking unprecedented cost advantages:

  • 150 €/kW stack cost – beating the industry’s most aggressive pricing targets
  • highest current density at moderate temperature (controlled durability risk)
  • lower material cost & secure (internal) supply chain for critical components (IrO2, Pt, PEM) 
  • optimized production efficiency & yield leveraging our CCM GW-factory 

Groundbreaking Test Results:

Our 50 μm MEA design is undergoing rigorous validation in real stack environment, having passed crucial milestones:

– stack validation in progress (1100 h completed)

  • cell design: 50 μm PEM, 1.0|0.4 mgIr|Pt/cm2, proprietary PTL & BPP 
  • stack design: 1350 cm2, 10 cells, flow field optimized for thin CCM
  • testing environment: customers’ 100 kW PEMWE stack test platforms 
  • KPI: <1.81 V @3.5 A/cm², 65 °C, 1.8 MPaH2; H2-in-O2 <0.15%
  • total runtime: 1,100 hours (as of 2025-04-21, ongoing)

– Sub-scale long-term test (@ constant current)

  • test setup: 25 cm2 single cell, ambient pressure, same MEA design as in stack 
  • KPI: <1.8 V @3.5 A/cm², 65 °C
    avg. voltage attenuation: ~3 μV/h (declining trend)
  • total runtime: 6,660 hours (as of 2025-04-21, ongoing)
