Humidification image 1Description:

ElectroChem’s HSA™ humidifier unit is used to provide humidification to two reactant gas supply lines for the electrochemical testing of PEM, alkaline and phosphoric acid fuel cells. It provides enough capacity for single cells and fuel cell stacks. This unit is often used to support the MTS-150™, MTS-A-150™ and ECL-150™ units to provide manually controlled fuel cell testing.
