The SulfaTrap™-SO - a Unique Sorbent/Catalyst Blend that Achieves Deep Purification of Cathode Air Intake

Cathode air intake may contain contaminants such as sulfur oxides (SO2, SO3) and carbon monoxide (CO) that can poison the electrocatalyst.

These impurities are of particular importance in transportation systems where nearby combustion engines release contaminants harmful to the fuel cells.

  • Ambient Temperature Operation

  • High Selectivity

    High selectivity to all airborne sulfur species, including:

  • High Removal Efficiency

    Sulfur concentration is reduced to less than 5 ppbv

  • High Capacity

    Long Operating Life

  • Moisture Tolerance

    High tolerance to moisture and CO2

  • Easy Disposal

SulfaTrap offers full service engineering, design and construction services including modular fabrication, field services and material and process support.

SORBENTS FOR FUEL CELL PROTECTION

SulfaTrap™-SO

The SulfaTrap™-SO is available as pellets, granules or in honeycomb structure engineered to minimize pressure drop. In addition to the sulfur sorbent, this material uses an ambient temperature catalyst to oxidize CO, formaldehyde and other volatile organic compounds (VOCs) to CO2 to provide protection to the Polymer Electrolyte Membrane (PEM) fuel cells.
