BriLyzer® PEM stacks cover R, S, T, and M series with capacities from 1 to 600 Nm³/h. They leverage multi-scale, multi-physics simulations for precise thermal, electrical, and mass-transfer modeling. Core technologies overcome key challenges including mass transfer under high-current conditions, plate corrosion, and high-pressure sealing. A high-reliability manufacturing system is established based on multi-stage self-sealing technology and high-precision stacking processes. The product is widely applicable in renewable energy-based hydrogen production (green hydrogen, methanol, ammonia, SAF), green metallurgy, hydrogen energy storage, and electronic semiconductors.
