Fuel Cell Solenoid Valve

for Automotive Fuel Cell

  • Regulates the pressure of hydrogen gas supplied form tank to fuel cells.
  • Controls the downstream pressure (supply pressure) according to the input current.


Without any sliding component, fuel cell valves incorporating a metal bellows offer low friction and low leakage.

By equalizing the pressurized areas of the valve and bellows, the effects of upstream pressure fluctuations are cancelled.

Solenoid thrust characteristics are optimally designed to reduce the effects of downstream gas usage (flow rate) fluctuations.

Consequently, this fuel cell valve is highly stable and responsive due to a structure that enables the controlled downstream pressure and solenoid thrust to be in balance when controlled.
