| High Light | 316L stainless steel flow field plate ，hydrogen fuel cell PEM electrolyzer plate ，0.1mm fine flow channel plate | ||
Our etched flow field plates are engineered for high-performance hydrogen fuel cells and PEM electrolyzers. Manufactured using advanced photochemical machining (PCM) technology, these plates deliver exceptional flow channel precision, ultra-thin profiles, and outstanding corrosion resistance — ensuring reliable long-term operation in demanding electrochemical environments.
| Fine Flow Channel Design | Optimized channel geometry (0.2–1.0mm width) ensures uniform gas distribution and efficient water management |
| Ultra-Thin Etching (0.1mm+) | Reduced stack height and weight, enabling compact and lightweight fuel cell designs |
| Long-Life Corrosion Resistance | 316L stainless steel and titanium alloy options withstand acidic PEM environments, passing ASTM G48 corrosion testing |
| High Precision (±0.01mm) | Photochemical etching guarantees consistent channel depth and width across the entire plate surface |
| Burr-Free & Stress-Free | Non-contact chemical etching eliminates mechanical stress, burrs, and micro-cracks |
High dimensional accuracy
Uniform flow channels
Smooth channel walls
Excellent corrosion resistance
Custom channel patterns
Our precision etching process enables the production of microchannels with excellent consistency while avoiding thermal distortion or mechanical stress.
Typical capabilities include:
Chemical etching (also known as photochemical machining) is a subtractive manufacturing process that uses chemical solutions to dissolve metal precisely. Unlike traditional stamping or machining, etching creates burr-free, stress-free plates without mechanical force. This allows for complex micro-flow channel designs, tight tolerances, and rapid prototyping, making it ideal for the intricate structures required in bipolar plates.
