Modern naval vessels utilize electrolytic oxygen generators to produce breathable air from deionized feedwater during prolonged submergence. While the electrolysis process cleanly separates water into hydrogen and oxygen gases, the generated hydrogen poses a severe combustion hazard if allowed to accumulate. To prevent explosive concentrations, the system continuously vents separated hydrogen overboard through high-pressure discharge lines, while routing the oxygen through catalytic scrubbers into the ship's internal atmosphere. If the external discharge manifold experiences backpressure or blockage, automatic fail-safe sensors immediately halt electrolysis before hydrogen levels in the generating cell can rise.
Which of the following conclusions is most logically supported by the passage?
- AThe automatic fail-safe sensors activate only after hydrogen concentrations reach dangerous levels.
- An obstruction in the external discharge system will cause the generation of breathable oxygen to stop.Cevap
- CHydrogen gas is routed through catalytic scrubbers into the vessel's internal atmosphere.
- DElectrolytic generators serve as the crew's exclusive source of breathable air throughout an entire mission.
