As the hydrogen industry moves from demonstration projects toward industrial deployment, electrolyzer manufacturers face increasing pressure to improve performance, accelerate product development and establish reliable component supply chains.

At Hydrogen Technology World Expo 2026 in Hamburg, Yianteng Special Anodes will demonstrate how its integrated manufacturing approach can help address these challenges. The company will showcase porous transport layers, including sintered titanium PTLs and titanium felt, together with customized bipolar plates for PEM, AEM and SOEC electrolyzers and PEM fuel cells.

Rather than supplying isolated manufacturing processes, Yianteng brings together material processing, precision chemical etching, coating, surface treatment, testing and scalable production. This integrated approach helps customers shorten the path from initial flow-field design and prototype evaluation to stack-ready components and repeatable series production.

ULTRA-THIN PTLs FOR RELIABLE INTERFACIAL CONTACT

Yianteng’s sintered titanium porous transport layers are available in thicknesses down to 0.08 mm. With a controlled pore size of 4–10 μm, low surface roughness and a compression-stable titanium structure, the PTLs are designed to support uniform water distribution, efficient oxygen removal and reliable contact with the catalyst layer.

Optional platinum and other functional surface coatings can be applied according to operating requirements. These treatments help maintain low interfacial resistance and long-term stability under the acidic and highly demanding conditions found in PEM electrolysis.

For applications requiring high porosity and greater conformity under compression, Yianteng also supplies titanium-felt PTLs. Their three-dimensional fibre structure supports effective water and gas transport while adapting to stack assembly tolerances.

PRECISION-ETCHED BIPOLAR PLATES FOR FASTER DEVELOPMENT

Yianteng manufactures customized flow fields through die-free precision chemical etching, with an etching accuracy of ±100 μm. Without the need for conventional forming tools during early-stage development, customers can modify channel patterns and evaluate new designs with lower initial tooling investment and shorter iteration cycles.

The company supports serpentine, parallel, interdigitated and application-specific flow-field geometries. Precision etching can be combined with CNC finishing and tailored surface treatments to meet requirements for electrical conductivity, corrosion resistance, sealing and dimensional consistency.

For electrolyzer applications, Yianteng provides an integrated bipolar plate solution combining precision chemical etching and advanced functional coating technologies. From customized flow-field development and prototype iteration to coating application, inspection and scalable production, the company supports customers through the complete component development process. This integrated approach reduces coordination between multiple suppliers, shortens development cycles and helps ensure consistent dimensional accuracy, electrical conductivity, corrosion resistance and interfacial performance.

FROM COMPONENT DEVELOPMENT TO SCALABLE SUPPLY

Yianteng operates a 37,000-square-metre production site in the Shuyang National Economic and Technological Development Zone in Jiangsu, China, including more than 20,000 square metres of modern production facilities.

Automated etching and coating lines are supported by an in-house testing laboratory equipped for electrochemical, dimensional, material and surface analysis. Full-process quality control—from incoming materials and production parameters to finished-component inspection—is designed to ensure precision and batch-to-batch consistency as customer projects progress toward larger production volumes.

Electrolyzer manufacturers need more than individual parts. They need component partners that can respond quickly during development and maintain consistent quality as projects scale. By combining PTL manufacturing, precision flow-field development, coating and testing, YIANTENG aims to make that transition more efficient for customers around the world.

Visitors are invited to meet the Yianteng engineering team at Hall , Booth 6E20 to discuss PTL, bipolar plates, customized flow-field designs, coating requirements, sample development and production projects.
