Flexible, multi-cartridge, reconfigurable/selectable air contaminant control system and method for fuel cells

摘要

A unique, multi-cartridge, easily re-configurable ambient air filter assembly (air contaminant control system) that removes particulate and gaseous chemical/biological contaminants from the incoming cathode air stream on a fuel cell or similar devices is described. The filter assembly is composed of individual filter cartridges (sub-assemblies) of various filtration media that are targeted at removing specific airborne contaminants. Combining specific sets of cartridges enables the filter assembly to be readily/rapidly configured (and re-configured) for specific applications—such as urban, rural, industrial, or military battlefield environments. Selection of correct media ensures complete removal of potential contaminants, enables rapid re-configuration to different environments, quick replacement of spent cartridges without disposal of non-spent media (reducing waste and cost). The invention concept is highly configurable to various sizes and shape fuel cells or other applications requiring clean ambient air by simply scaling the filter assembly size and air flow rates.

主权项

1. A fuel cell cathode air filter assembly or air contaminant control system comprising:
an intake port that collects ambient air and directs it into the filter assembly; a filter housing comprising a plurality of retainers and a removable panel that permits access to the filter housing; a filter assembly comprising a plurality of individually configurable and separately removable filter cartridges arranged within the filter housing, wherein each filter cartridge fits within one of the retainers of the filter housing, and wherein each filter cartridge is surrounded by a compressible material; and an outlet port assembly that connects to the oxidant intake port of the fuel cell or other device that requires clean ambient air.
