Core Viewpoint - The article discusses the advancements in PEM (Proton Exchange Membrane) electrolysis technology, particularly focusing on the development of low iridium-loaded membrane electrodes by Suzhou Qindong Technology, which aims to reduce costs while maintaining performance and durability in green hydrogen production [2][3][19]. Industry Overview - The PEM electrolysis industry is still in its early stages compared to the mature alkaline electrolysis sector, with PEM systems currently holding only about 5% market share in domestic green hydrogen demonstration projects [2]. - The initial investment cost for PEM electrolysis systems is 3-5 times higher than that of alkaline systems, making cost reduction a primary goal for industry development [2]. Technological Innovations - Suzhou Qindong has developed a load-type IrOₓ/TiO₂ anode catalyst that achieves a low iridium loading of 0.5 mgIr/cm² without sacrificing performance or lifespan, aiming to bring the cost of PEM electrolysis systems below 1 million RMB per MW [2][5]. - The company addresses three main bottlenecks in reducing iridium loading: insufficient catalytic active sites, mechanical strength of the catalyst layer, and electron conduction pathways [4][5]. Performance and Durability - The new HPCW-R950C membrane electrode demonstrates superior durability, with an activation polarization decay of only 8.3 mV after 50,000 square wave cycles, significantly outperforming competitors [17][20]. - In long-term aging tests at 80°C and 3 A/cm², the product shows an average decay rate of just 4.2 μV/h, indicating a projected lifespan exceeding 40,000 hours [17][21]. Manufacturing and Market Position - Suzhou Qindong has established itself as one of the few domestic suppliers capable of independently developing and mass-producing catalysts and membrane electrodes, with 142 patents filed, of which 109 have been authorized [19][23]. - The company utilizes advanced roll-to-roll coating techniques to ensure high precision and efficiency in manufacturing, achieving a stable yield rate of over 95% [22][23]. Future Outlook - The company aims to continue focusing on durability, performance iteration, and cost optimization to drive further advancements in PEM membrane electrode technology, contributing to the green hydrogen industry and global energy transition [23].
