Hydrogen-Powered Fuel Cell Silicone Hose

Rainbow Manufacturing develop fuel cell silicone hoses for hydrogen-powered vechiles, rail train and ship since 2017.

The hydrogen fuel cell silicone hose meets standard ANSI/CSA HGV 4.2-2013. 

Silicone Lines for Hydrogen-Powered Fuel Cells

Fuel cell vehicles use a fuel cell to generate electrical energy from hydrogen or methanol energy carriers; that electrical energy is then converted directly into movement via the electric drive or temporarily stored in a traction battery.

Rainbow Manufacturing offers silicone lines for thermal management, fuel supply and air intake for fuel cell drives.

Due to their specific operating conditions, the silicone lines must be flame retardant and must demonstrate low electrical surface resistance. Media resistance in high-purity cooling water is especially important to ensure that the functional capacity of the fuel cells is not jeopardized.

The silicone lines has fire rating UL94-V0 level and meets standard EN45545.

Charge Air Hoses for Fuel Cells

The silicone hose is based on our proprietary high-quality silicone material, which contains an extremely low proportion of volatile compounds in order to ensure the long-term functional reliability of the sensors and the membranes within the fuel cell.

Technical specifications & benefits

1. An extremely pure peroxide crosslinked silicone (VMQ) compound for inner and outer hose layers with knitted reinforcement

2. Operating temperatures of up to 200°C (continuous) and 250°C (peak)

3. Operating pressures in excess of 3 bar

4. Extremely low proportion of volatile compounds at operating temperature to prevent interference to sensors and membranes within the fuel cell

5. Optimal cleanliness of components

Cooling Water Hoses for Hydrogen-Powered Fuel Cell Vehicles

A special material has been developed to meet the particular demands of cooling circuits for fuel cell applications.

Technical Specifications and Benefits & Features

1. An extremely pure peroxide crosslinked FKM compound for the inner lining and outer layer of knitted hoses

2. Resistance to distilled water and water ethylene glycol mixtures

3. Resistance to air temperatures of up to 200°C

4. No extractable components that can result in an excessive increase in the specific conductivity of deionized water

5. No forbidden particle contaminants

6. Prevention of electrostatic charges due to surface resistance < 1 gigaohm as per EN 50014

7. Full compliance with the functional requirements as defined in DIN 73411

Rainbow Manufacturing developed Viton lined silicone hose which has FKM liner that has good perfornance for fuel cell power system. Welcome to contact us for more details of hydrogen-power fuel cell silicone hoses.
