Electrolyzer Controller

Embedded Controller with Stack Voltage/Current Profile

The electrolyzer controller is an embedded, radiation-tolerant unit that regulates stack current, water feed, and gas production rates within lunar life-support water processing chains. Operating at a 10 Hz control loop rate on 2 W of power, it adjusts oxygen output to habitat demand using constant-current control with a voltage compliance limit. Because space radiation threatens digital logic, the controller executes firmware from rad-hard NOR flash on radiation-tolerant processors, relying on autonomous hardware interlocks that bypass software during sensor faults to maintain safe differential pressures and prevent catastrophic hydrogen-oxygen crossover.
