Typical Application:
- Hydrogen Flow Control: Precise fractional flow regulation of hydrogen supply to maintain required flow conditions within a fuel cell system.
- Hydrogen Pressure Regulation: Reducing or controlling hydrogen gas pressure between the supply source and downstream components using high-pressure low-flow or piston-operated pressure regulators.
- Fuel Cell Pressure Regulation: Managing inlet or outlet pressure during stack operation, development, and performance testing.
- Back Pressure Control: Maintaining controlled upstream pressure in hydrogen fuel cell and gas-handling systems using gas back pressure regulators.
- Fuel Cell Test Systems: Accurate flow and pressure control for laboratory, development, and performance-testing equipment where repeatable, drift-free gas control is essential.
- Hydrogen Gas Distribution: Valve and regulator solutions for hydrogen supply distribution and gas-handling requirements associated with fuel cell equipment.
