Build the World’s Most Efficient PEM Stacks
Cube Electrolysis empowers electrolyzer manufacturers to set a new industry benchmark – without expensive lead time for development.
Our Technology
2D Thin-Film Cell Architecture
A proprietary cell design that reimagines PEM electrolysis from the ground up. By leveraging 2D thin-film principles, we achieve record efficiency while dramatically reducing material costs and system complexity.
Lab-to-Scale Performance
Maintaining record CCM efficiencies at industrial dimensions. Our architecture translates lab-scale performance to industrial active area size without scaling losses.
Cost Benchmark
Just 2D cuts from standard sheet materials and highest current densities. The foundation for the lowest production costs and highest utilization of precious metals.
Simplified Assembly
Fewer parts, fewer failure points. The streamlined design reduces manufacturing complexity and enables faster production cycles.
Customized Scalability
Application-optimized stack design for minimum cost. The 2D thin-film architecture enables customized cell sizes and cell counts for every specific use case.
