Fuel Cell Gas Control Valve - GCV

Fuel Cell Gas Control Valve (GCV) is designed to regulate the air flow and pressure in the cathode path of a fuel cell system.

The GCV can be used as a bypass valve or as a valve to control the pressure of the system.

By acting as a bypass valve, the GCV guides fresh air from the intake to the exhaust.

It can also bypass the fuel cell stack or just the humidifier.

Usage to either bypass flow or increase backpressure.

Its electrically driven valve plate is able to continuously open and close flow paths in the air system of a fuel cell system.

This regulates the air mass flow and the pressure of the fuel cell stack.

Flexible application options and continuously adjustable valve positions with low pressure drops ensure efficient and safe operation of the fuel cell system.

Highly effective regulation of air flow and pressure of cathode path.

Highly flexible to ensure efficient and safe operation of fuel cell systems in various applications.

Fast opening butterfly valve concept with high flow cross section (up to 65 mm) for very low pressure drops at high mass flow.

Technology derived from Acoustic Valve Generation 2 used in automotive series production in passenger cars.

Key features

Developed based on the Acoustic Valve Generation 2 (produced in series).

Designed with additional sealing solutions and decreased gaps to reduce internal and external leakage.

Low pressure drop at high mass flow.

Different communication input signals for the actuator are possible.

Positioning: 0 – 90° continuously adjustable valve plate.

Position Accuracy: +/- 2

PWM control signal available.

LIN and CAN control signal possible.

Generic validation based on LV124.

Material: stabilized austenitic materials for high corrosion stability.

Connection Pipe Diameter: Ø 65 mm (different flanges can be welded).

Connector: 4-pin Hirschmann ML.

Operating temperature from -40°C to +140°C.
