摘要： Adjustment of the noble metal catalytic activity in the production of noble metal alloyed catalyst preparation using alloying metals capable of multiple valence states improves the alloying metal loading. A noble metal is precipitated from a liquid onto a support. Prior to the addition of an alloying metal which is capable of a low valence state having low solubility and a high valence state having high solubility, the catalytic activity of the noble metal precipitate is reduced. Reduction is accomplished by adjusting the temperature and/or pH of the liquid such that a minimal amount of the alloying metal will be converted from the lower to the higher valence state. By maintaining the alloying metal in the lower valence state, a greater amount of the alloying metal which has been dissolved into the liquid is precipitated onto the support, thereby attaining high loadings, reducing waste of the alloying metal, making the loadings predictable, and making the waste liquid more environmentally sound.

摘要： An arrangement is provided in a fuel cell power plant (10) for dispensing (58 74, 60, 64) a liquid medium, such as water (66), into a process oxidant (air) stream (53) that flows through one gas channel (42) in an energy recovery device (ERD) (32). An exhaust gas stream (48) containing heat and moisture from the fuel cell (12) flows through another channel (44) in the ERD. An enthalpy exchange barrier (46) separates the one and the other gas channels, but allows mass and/or heat transfer therebetween. The water is injected into the air stream (53) in a controlled (70, 74) amount, and perhaps temperature (78), in response to sensed parameters (80, 84, 90) of the power plant, including the process air stream, to adjust one or more conditions in the power plant. Controlling ERD dryness, providing a defrost capability for the ERD, and/or preventing excessive water accumulation in the system are several of the conditions controlled.

摘要： Method and apparatus are provided for removing contaminants from a hydrogen processor feed stream, as in a fuel cell power plant (110). Inlet oxidant (38), typically air, required by a catalytic hydrogen processor (34) in a fuel processor (14) for a fuel cell stack assembly (12) in the power plant (110), may contain contaminants such as SO2 and the like. A cleansing arrangement, which includes an accumulator/degasifier (142, 46) acting as a scrubber, and possibly also a water transfer device (118), receives the inlet oxidant and provides the desired cleansing of contaminants. Water in the water transfer device and in the accumulator/degasifier serves to dissolve the water-soluble contaminants and cleanse them from the oxidant stream. The cleansed oxidant stream (138′) is then delivered to the hydrogen processor and to the fuel cell assembly, with minimal inclusion of detrimental contaminants such as sulfur.

摘要： An apparatus 124 using an aqueous solution consisting essentially of water for forming a compound which retards the deposition of iron-based compounds is disclosed. The apparatus includes a chamber 138 for forming steam which is injected through a nozzle 148 into a chamber 136. The pH of the aqueous solution, which is acidic, is raised in the presence of oxygen to cause Fe++ to come out of solution as a precipitate and the oxygen level is lowered to limit the growth in size of the precipitate.
