APT has developed a series of exclusive component BOPs for Xell™ stack, including back-pressure valves, flow diverter valves, hydrogen injectors, gas-liquid separators, hydrogen recirculation pumps, etc., to provide customers with a wide range of selection for developing their fuel cell power systems.
Cathode Air Control Valve
- To regulate air pressure supplied to the fuel cell stack.
- Butterfly valve ensures low pressure loss and excellent flow control.
- Special mechanism design maintains operability and corrosion. resistance at temperatures below freezing point.
- The impermeable coating prevents the water that penetrates into the space between the valve and the hole from freezing.
Hydrogen Injector
- Sophisticated hydrogen supply technology simultaneously adjusts the anode hydrogen inlet pressure and flow rate.
- Three ejectors in tandem improve the stability and reliability of hydrogen supply.
- Modular design with small size and lightweight.
- PWM control responds to the change in operating conditions from idling to high duty.
Hydrogen Circulation Pump
- Special double-lip seal design provides a gastight environment for hydrogen circulation.
- Special coating on the blade surface provides high-performance lubrication conditions.
- Integrated design of the hydrogen circulation pump and the stack endplate improves the heat dissipation performance of the motor and achieves a more compact system size.
Gas-Liquid Separator
- Patented spiral-shaped cyclone structure separates water droplets through centrifugal force.
- Patented hydrophilic filter removes out macromolecular water vapor.
- Secondary exhaust flow path design reduces the possibility of freezing and blocking in the channel connection.
- Combining the hydrogen circulation pump makes the fuel cell system more compact.
