The anode recirculation blower is a key component in the hydrogen path of a fuel-cell system. It is actuated via a CAN interface and conveys, in combination with a jet pump, the hydrogen that has not been consumed (due to an operating surplus) from the stack and back to the hydrogen infeed. In addition, the anode recirculation blower separates water from the hydrogen circuit and conveys it out of the anode path via an additional valve just as it does to the diffused nitrogen.

broad spectrum of applications

The component performs additional functions such as water separation in the anode circuit and conditioning/purging of the stack anode path when starting up/shutting down.

small installation space and low weight

thanks to highly compact design and integrated electronics

low power consumption

Through combination with a jet pump, the component covers the entire requirements range with minimal power consumption.
