Find and compare hydrogen blowers for fuel cell systems using technical specifications. Sometimes also referred to as a Hydrogen Recirculation Blower (HRB) or an Anode Recirculation Blower (ARB) they are included in the anode (hydrogen) loop of fuel cell systems. Essentially, they enable a controlled return of unused hydrogen into the fuel cell stack thereby significantly increasing fuel efficiency. They can also foster an increased lifespan of the fuel cell stack through enabling a more homogeneous distribution of hydrogen across the cells. Various compression technologies are used such as claw compressors or diaphragm compressors, however in all cases special seals and coatings are required so as to resist corrosion by the deionized liquid they are typically exposed to.
