Fuel Cell Cathode Isolation Valve - CIV

Fuel Cell Cathode Isolation Valve (CIV) is used in the cathode path of a fuel cell system.

It is designed for an airtight seal of the inlet and outlet of a fuel cell stack when the system is switched off.

Due to the airtight seal, the conditions in the fuel cell stack will be constant during a switched off system.

This prevents premature aging of the fuel cell stack and enables a quick restart of the fuel cell system.

Seals the inlet and outlet of a fuel cell stack system airtightly to minimize leakage.

A fail-safe function is included ensuring a safe closing of the fuel-cell stack when needed.

The electrical actuator of the CIV is able to continuously adjust the valve position.

This allows for precise regulation of mass flow and fuel cell stack pressure.

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

Key features

Valve with sealing solution to minimize internal and external leakage.

Valve can be mounted directly to the fuel cell stack.

Different communication input signals for the actuator are possible.

Valve is planned in different diameters (flow cross section).

Material: stabilized austenitic materials and aluminum alloys for high corrosion stability.

Input Signal: PWM Smart possible/ Non Smart available.

Positioning: 0 – 90° continuously adjustable valve plate.

Position Accuracy: +/- 2

Connection Pipe: Flange with 3 screws.

Connector: 5-pin Hirschmann ML.

Diameters: Inlet: 55.8 mm / Outlet: 45.0 mm.

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