Provide solutions for key materials of fuel cell system, including metal gas diffusion layer, metal bipolar plates and fuel cell stack. Our metal GDLs have been supplied in mass production to international high-tech companies. For metal BBPs and fuel cell stacks, we are the top suppliers in China.
Features are as below:
• Titanium-based Metal Gas Diffusion Layer: High porosity with enhanced waterproofing and permeability, excellent mechanical properties under fuel cell operating conditions
• Metal Bipolar Plates: low contact resistance and superior anti-corrosion performance, achieved by customized flow field design and optimal metal anti-corrosion coating.
• Self-humidifying Fuel Cell Stack: Low volume, high power density, stable performance and long-life extension with fast cold start, self-detection and alarm features.
Typical applications are as below:
• Titanium-based Metal Gas Diffusion Layer：In mass production, qualified suppliers of international hi-tech companies.
• Fuel cell stack: 5kW, 10kW, 10kW, 20kW, 30kW, 60kW series in production.
