The Challenge

1
Material durability and performance
AEM membranes, electrodes and interfaces must combine high efficiency, high current density and long-term stability under alkaline operation, dynamic loads, pressure cycling and start-stop conditions.
2
Safe and flexible operation
AEM systems must operate safely across the full load range, from low-load renewable operation to high-current-density regimes, while controlling gas crossover, parasitic currents and transient risks.
3
Fluid, thermal and pressure management
Uniform electrolyte distribution, efficient gas removal, and controlled heat and pressure gradients are essential to avoid hotspots, flooding, dry-out, leakage and non-uniform ageing.
4
Mechanical integrity and scalable manufacturing
Frames, seals, bipolar plates, gaskets and MEAs must maintain tight tolerances, leak-tightness and low contact resistance, while being compatible with automated, reproducible and low-defect manufacturing.
5
System integration with renewable power
Stacks must be integrated with BoP components, power electronics, controls and safety systems able to manage fast renewable power fluctuations in grid-connected, off-grid and hybrid scenarios.
6
Market competitiveness and certification
AEM electrolysis must reduce hydrogen production costs through lower CAPEX, longer lifetime, reduced critical raw material use and scalable production, while meeting clear safety, testing and certification requirements.
