Recently, the research results jointly completed by Lead Hydrogen Intelligent, a subsidiary of Lead Intelligent, and Shanghai Jiao Tong University were officially published in the international journal Fuel Cells (2026). This study first established a quantitative analysis method from equipment parameters to coating quality for the roll-to-roll narrow gap coating of fuel cell catalytic layers. It precisely quantified the impact mechanism and transmission rules of two types of equipment disturbances – coating die deformation and back roller runout – on wet film thickness. It proposed practical optimization paths such as the “balance sweet spot area” of gasket thickness and the stable coating window of back roller runout, and constructed a full-chain analysis framework of “equipment-process-product”, providing solid theoretical support for the mass production and consistency of catalytic layers.<\/span><\/p>\n

In the batch manufacturing of fuel cell catalytic layers, the stability of equipment operation directly determines product consistency, <\/span>commissioning<\/span> efficiency, and line scaling capability. However, the core contradiction of a production line often hides in the transmission path of micro-meter-level deviations of equipment.<\/span><\/p>\n

When low-speed <\/span>commissioning<\/span>, the film thickness is uniform and the state is stable. Once<\/span> the speed increases and the width is increased<\/span>, uneven thickness and longitudinal periodic fluctuations appear immediately. A few micrometers of coating die deformation or back roller runout, after being transmitted through the slurry flow field and coating liquid bridge, eventually amplify into noticeable wet film defects.<\/span><\/p>\n

This is exactly the problem that is repeatedly encountered in mass production but difficult to answer: Why does the equipment precision meet the standards, yet the product performance remains unstable?<\/span><\/p>\n

Recently, the latest research results jointly completed by Lead Hydrogen Intelligent and Shanghai Jiao Tong University were officially published in the internationally renowned journal Fuel Cells (2026) in the hydrogen energy field. This study first established a quantitative link from equipment parameters to coating quality for the roll-to-roll narrow gap coating of fuel cell catalytic layers. It precisely quantified the impact of coating die deformation and back roller runout on wet film thickness, providing solid theoretical support for the mass production and consistency of fuel cell catalytic layers.<\/span><\/p>\n
