Non-precious metal coating for fuel cell bipolar plates

One of the main components of the fuel cell is the bipolar plate stack. NanoShield's PVD non-precious metal coating has obvious cost-effective advantages and is an effective attempt to replace gold and platinum precious metal materials. Naxau first-generation composite titanium nitride coating can maintain good electrical conductivity and low contact resistance under galvanic corrosion environment for a long time. We are also collecting data on the application of non-precious metal PVD programs on hydrogen energy storage.Naxau is actively promoting and optimizing the production line of fuel cell bipolar plate processing equipment. Efficiently and cost-effectively lowering the threshold of hydrogen energy popularization.

01 Advantages of Naxau non-precious metal series PVD bipolar plate cells

Naxau bipolar plate protective coating, which has entered the pilot stage, is already better than the industry average in terms of corrosion potential and ICR: Interface Resistance. The second generation of NanoShield's hydrogen fuel cell coatings are still doped non-precious metal PVD coatings. We have deep cooperation with universities and colleges to maintain the industry's top level.

02 Cooperation on hydrogen energy coating projects

Naxau always maintains cooperation with domestic and foreign scientific research institutions, and has a new energy academician workstation. At present, we have a certain pioneering advantage in new energy fields such as hydrogen energy, bipolar plate, composite fluid collector and so on. We provide bipolar plate coating sampling service, vacuum coating machine and process sales, a complete set of production line program design multi-way cooperation.

We can provide a complete package for bipolar plate production, pre-treatment and coating delivery from scratch.

04 Partial Parameters of Fuel Cell Bipolar Plates

• Common materials: stainless steel, titanium, graphite;
• Bipolar plate thickness: 0.05-0.2mm;
• Runner width: 0. 5~2. 5mm; runner depth: 0. 2~2. 5mm; size deviation: ≤8%;
• Roughness of runner bottom: Ra≤1.6μm;
• Inclination angle of the runner: θ is 0° to 60°;
• Length of runner: The longer the runner, the greater the pressure loss, the lower the concentration of reaction gas in the final stage, thus reducing the performance of the cell;
