电解槽隔膜，确保安全高效
Electrolyzer diaphragms – ensuring safety and efficiency.
电解槽隔膜是电解水制氢过程中至关重要的组成部分，位于电解槽的两个电极之间，主要功能是有效隔离正负极，避免短路及提升电解效率。其性能直接影响电解槽的工作效率、氢气纯度以及系统的稳定性。初期采用石棉材质，之后发展为PPS隔膜，第三代为复合隔膜。其核心优势在于优化亲水性与电解液的相容性，大幅降低了电解槽的内阻。
An electrolyzer diaphragm is a critical component in the water-electrolysis hydrogen-production process, positioned between the cell’s two electrodes. Its primary function is to reliably separate the anode and cathode—preventing short circuits and boosting electrolysis efficiency. Diaphragm performance directly impacts the electrolyzer’s operating efficiency, the purity of the hydrogen produced, and overall system stability. Early designs used asbestos materials, which were later superseded by PPS (polyphenylene sulfide) diaphragms; the third generation employs composite diaphragms. These advanced separators optimize hydrophilicity and electrolyte compatibility, significantly lowering the electrolyzer’s internal resistance.
长期以来，电解槽隔膜市场被国际企业主导，其中日本东丽曾占据中国碱槽隔膜市场90%以上的份额。近年随着行业的持续迭代，尤其是配套设备的崛起，国产化率有所提升。精诚携手上下游企业，结合自身行业经验，对电解槽隔膜狭缝涂布模头优化设计，有效避免涂层过厚或不均匀的问题，解决了现有产品稳定性、耐久性和高成本等瓶颈，为国产化替代提供了有力支撑。
For a long time, the electrolyzer-diaphragm market has been dominated by international corporations—Japan’s Toray Industries once held over 90 % of China’s alkaline-electrolyzer-diaphragm segment. In recent years, thanks to ongoing industry evolution and especially the rise of supporting equipment, the domestic localization rate has steadily increased. JCTIMES with its upstream and downstream partners and, drawing on its extensive industry experience, optimized the design of the electrolyzer-diaphragm slit coating die. This innovation effectively prevents excessively thick or uneven coatings, overcomes existing bottlenecks in product stability, durability, and high cost, and provides strong support for domestic substitution.
CCM膜电极，提升电池性能
CCM membrane electrode – enhancing cell performance.
CCM膜电极是氢燃料电池的核心组件之一，直接决定着电池的性能、寿命与成本，犹如电池的“心脏”。CCM膜电极的关键技术在于催化剂涂层的优化，其涂布工艺直接影响催化剂的利用率和电池的耐久性。
The CCM membrane electrode is one of the core components of a hydrogen fuel cell, directly determining the cell’s performance, lifespan, and cost—much like the “heart” of the battery. The key technology for CCM membrane electrodes lies in optimizing the catalyst coating; its coating process directly affects catalyst utilization and the cell’s durability.
精诚在膜电极涂布技术上不断创新，推出了双层双闭环涂布模头。这一技术能够灵活实施间歇涂布和斑马涂布，从而更好地满足不同领域的需求，特别是在低空飞行器、高寒、高负载以及长时间运行等特殊工况下的应用。在提升氢能燃料电池效率、降低生产成本和延长使用寿命方面取得了显著成果。
JCTIMES continues to push the boundaries of membrane-electrode coating technology with its dual-layer, dual-closed-loop coating die. This innovation enables both intermittent and “zebra” coating patterns, precisely tailored to diverse application requirements—especially under demanding conditions such as low-altitude UAVs, extreme-cold environments, high-load operations, and prolonged runtimes. It has delivered significant gains in hydrogen fuel-cell efficiency, reduced manufacturing costs, and extended service life.
