Solar hydrogen fuel cell system
Architecture
U.S. Patent No. 12,712,480 issued 18 August 2026
Architecture
The system employs rSOC stacks with graded porosity electrodes and infiltrated nanocatalysts operating alternately in electrolysis and fuel cell modes. A predictive control system using LSTM neural networks forecasts conditions 72 hours ahead, selecting between five operational modes.
Dynamic stack reconfiguration eliminates power electronics losses by matching solar voltage variations.
