Abstract
A fuel cell system is specially adapted to provide enhanced air purification for stationary and mobile applications. An air purification subsystem may be installed along a cathode flow path to enhance air purification by utilization of fuel cell operating conditions. Synergistic automotive, residential, commercial and agricultural applications are thus provided. Air purification subsystems may include, for example, a multi-purpose platinum-based catalyst configuration adapted to convert carbon monoxide into carbon dioxide and ozone into diatomic oxygen.
