两大进展：青骐骥电解槽投运、动量守恒AEM蜂窝电极发布

Core Viewpoint - The article highlights advancements in hydrogen production technology, specifically focusing on the new generation of electrolyzers developed by Qingqi Ji, which demonstrate significant improvements in energy efficiency and performance metrics compared to previous models [2][3][4]. Group 1: Hydrogen Production Technology - Qingqi Ji has added two 1000 Nm³/h electrolyzers to the renewable energy hydrogen production demonstration project at PetroChina's Yumen Oilfield, creating a "4-to-1" hydrogen production system [2]. - The new electrolyzers have achieved record-breaking performance in energy consumption and degradation rates, setting a new industry benchmark for hydrogen production efficiency [3]. - The energy consumption metrics for the new electrolyzers have been confirmed by an international third-party certification body, showing a reduction in energy consumption to 3.99 kWh/Nm³H₂ at 4000 A/m² current density, a decrease of approximately 3.4% compared to the previous model [4]. Group 2: Innovative Electrode Technology - Momentum Conservation has successfully developed a high-consistency self-supporting nickel-based porous transport electrode (Ni-PTE), which is expected to enhance hydrogen production efficiency and system durability in AEMWE applications [6]. - The new honeycomb electrode structure allows for uniform catalyst distribution and high product consistency, with batch production capabilities already established [6][8]. - In stability tests exceeding 1000 hours, the honeycomb electrode demonstrated low potential decay rates of 18.6 μV/h and 35.2 μV/h when paired with different commercial AEM membranes, indicating strong durability and reliability [9].
