Requirements for dimensions and flow channel structures of electrodes and bipolar plates vary greatly in hydrogen energy and electrochemical industries, and general processing solutions cannot satisfy personalized working conditions of different projects. In identical application scenarios, precise etching structure design can optimize fluid distribution and reduce ohmic loss, so as to improve the overall operating performance of electrodes and stacks. 

Supported by sophisticated etching technology, we develop customized etching solutions for flow channel layout, microporous structure and porous transport layer profile according to customers’ drawings and operating targets. Precision etching processing is available for fuel cell bipolar plates, metallic plates for PEM/AEM/SOEC electrolyzers, porous transport layers (PTL) and other products. Micron-level dimensional accuracy can be achieved to guarantee surface flatness and structural consistency. 

We provide integrated customized etching design and processing services based on customer demands, supporting the development of diversified electrochemical components.
