Abstract
Methods and apparatus for improving water management in a PEM fuel cell power supply are disclosed. The fuel cell power supply includes a combustion unit that combusts anode exhaust, producing combusted exhaust that includes water. The combusted exhaust is recycled to the anode input and/or the cathode input. The recycling system can include additional devices, for example, a CO removal device for removing CO from the combusted exhaust prior to recycling to the anode. A fuel processor can be thermally coupled to the combustion unit that combusts the anode exhaust. One advantage of the invention is that the condenser typically employed for recovering water from combusted exhaust can be eliminated, of reduced capacity or operated less frequently, thereby reducing the cost and/or the complexity of the fuel cell power supply.
