Direct electrolysis of liquid anhydrous ammonia for continuous production of high-purity, pressurized hydrogen at ambient temperature

The electrolyzer directly converts liquid anhydrous NH3 into pressurized, high-purity H2 (>5.5 bar, >99.99%) at 10 °C with a faradaic efficiency of >98.8%, eliminating the need for additional H2 purification and separation processes.
