Under the growing crisis of the coronavirus disease 2019 pandemic, the global medical system is facing the predicament of an acute shortage of medical-grade oxygen (O₂, ≥ 99.5% purity). Herein, an oxygen generation device is manufactured that relies on electrochemical technology. The performance of the electrochemical oxygen generator (EOG) is remarkably improved to a practically applicable level, achieving long-term (>200 h), stable, and quick production (>1.5 L min⁻¹) of high purity O₂ (99.9%) at high energy efficiency (496 L kW⁻¹ h⁻¹), via simultaneous optimization for intrinsic electrochemical reaction mechanisms, electrocatalysts, and external cell structure. The EOG also presents powerful competitiveness in user experience, which finds expression in high portability (4.7 kg), nearly instant O₂ production (<1 s), and a quiet working condition (<39 dB). The EOG shows great potential to substitute commercial pressure swing adsorption O₂ generation devices, which may significantly impact the traditional oxygen production industry.

氧气纯度达99.9%，能效高的电化学制氧机

在2019冠状病毒病疫情日益严重的危机下，全球医疗系统正面临医用级氧气（O ₂，纯度≥99.5%）严重短缺的困境。在此，制造依赖于电化学技术的氧气产生装置。电化学制氧机（EOG）的性能显着提升至实用水平，实现了长期（>200 h）、稳定、快速生产（>1.5 L min ^-1）高纯度O ₂（99.9% ） ) 在高能效下 (496 L kW ^-1 h ^-1)，通过同时优化内在电化学反应机制、电催化剂和外部电池结构。EOG在用户体验方面也呈现出强大的竞争力，体现在高便携性（4.7 kg）、近乎即时的O ₂生产（<1 s）和安静的工作条件（<39 dB）。EOG显示出替代商业变压吸附O ₂产生装置的巨大潜力，这可能会对传统的氧气生产行业产生重大影响。
