Resumen de: US20260159965A1
0000 This system uses a water electrolysis stack to split water into hydrogen and oxygen. Hydrogen is discharged at the negative electrode and stored in a hydrogen tank, while oxygen is discharged at the positive electrode and stored in an oxygen tank. The stored gases can be recirculated into the electrolysis stack as needed. Sensors measure hydrogen and oxygen concentration in the discharged fluid, and a controller compares these readings to safe limits. If a concentration is too high, valves automatically adjust to control the flow of stored gases. Additional components, such as an ejector and pressure controls, help ensure efficient operation and prevent unsafe gas buildup.
