HYDROGEN-PRODUCING FUEL PROCESSING ASSEMBLIES AND METHODS FOR DELIVERING FEEDSTOCK TO A HYDROGEN-PRODUCING REGION (19) OF A HYDROGEN-PRODUCING FUEL PROCESSING ASSEMBLY (10), IN SOME EMBODIMENTS, THE FUEL PROCESSING ASSEMBLIES INCLUDE A FEEDSTOCK DELIVERY SYSTEM (22) THAT INCLUDES A PUMP ASSEMBLY (100) AND A STALL PREVENTION MECHANISM (160) THAT IS ADAPTED TO REDUCE PRESSURE IN AN OUTLET CONDUIT (132) DURING PERIODS IN WHICH THE PUMP ASSEMBLY IS NOT EMITTING A LIQUID OUTLET STREAM (116) WITHIN OR ABOVE A HYDROGEN-PRODUCING PRESSURE RANGE. IN SOME EMBODIMENTS, PRESSURE IN THE OUTLET CONDUIT IS ISOLATED FROM PRESSURE IN THE HYDROGEN-PRODUCING REGION OF THE FUEL PROCESSING ASSEMBLY AND IS REDUCED DURING PERIODS IN WHICH A LIQUID STREAM (110) IS NOT BEING PUMPED WITHIN OR ABOVE A HYDROGEN-PRODUCING PRESSURE RANGE. |
