The Anode recirculation blower supports the hydrogen recirculation in the anode 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.
Is it possible to have more information on the h2 recirculation pump?
