Selective oxidizer in cell stack manifold

A compact integrated fuel cell stack and selective oxidizer assembly, comprising:

• a first fuel cell stack assembly comprising a plurality of fuel cells;
• a second fuel cell stack assembly comprising a plurality of fuel cells;
• a fuel inlet manifold adjacent to and in fluid communication with said first fuel cell stack assembly and adjacent to and in fluid communication with said second fuel cell stack assembly for directing a fuel supply to said fuel cells in said first fuel cell stack assembly and said fuel cells in said second fuel cell stack assembly;
• a fuel exhaust manifold arranged in fluid communication with said first fuel cell stack assembly and said second fuel cell stack assembly for exhausting said fuel supply from said fuel cells in said first fuel cell stack assembly and said fuel cells in said second fuel cell stack assembly;
• an internal selective oxidizer bed, having an input plenum and an output plenum;
• said internal selective oxidizer bed residing in said fuel inlet manifold;
• said output plenum being connected to said first fuel cell stack assembly and said second fuel cell stack assembly;
• said internal selective oxidizer bed including a selective oxidation catalyst with a heat exchange fluid conduit routed therethrough;
• said heat exchange fluid conduit being in contact with said selective oxidation catalyst;
• a fuel source connected to said input plenum of said internal selective oxidizer bed;
• said fuel source providing fuel into said internal selective oxidizer bed;
• an oxidant source connected to said input plenum of said internal selective oxidizer bed;
• said oxidant source being capable of providing oxygen into said internal selective oxidizer bed via said input plenum;
• and
• temperature control means provided in said internal selective oxidizer bed and connected to said heat exchange fluid conduit for controlling the temperature of said internal selective oxidizer bed.
