Abstract
An air COfiltration assembly or system is provided that includes COfilters or traps designed and configured with a limited, but high capacity, volume to maximize filtration/absorption of COfrom an air stream supplied to an alkaline fuel cell to thereby minimize the COlevel in the air stream fed into the fuel cell cathode. The COfilters or traps include at least one thermally regenerative COchemical filter or trap arranged in a tandem configuration with a strongly bonding COchemical filter or trap. The combination of the two types of filters or traps sequentially filter/absorb COfrom the air stream and reduce the level of COin the air stream fed into the cathode. The air COfiltration assembly or system may be used in conjunction with electrochemical purging of the alkaline fuel cell that enables removal of COfrom the fuel cell by anodic decomposition of accumulated carbonate ions in the fuel cell anode and release of COthrough the anode exhaust stream.
