摘要: According to the present invention, a temperature profile within a preferential oxidation reactor is controlled using a two phase water/steam system to provide a temperature range within the reactor (10) which favors the selective oxidation of CO in a hydrogen rich reformate stream. The reformate is flowed in a mixture with oxygen over a preferential oxidation catalyst (17). The temperature profile is controlled by flowing a stream of water proximate to the preferential oxidation catalyst (17) so as the stream of water and the reformate stream passing over the catalyst (17) are in a heat transfer arrangement. The stream of water is maintained as a two phase stream from a point at which the water reaches its boiling temperature to a point proximate an outlet from which the stream of water exits the reactor (10).

摘要: A fuel cell power plant comprises a fuel processor and a fuel cell stack. The fuel cell stack has cooling water directly passing through its anode or cathode compartments. The high humidity cathode exhaust may be used to provide oxygen and steam for the autothermal reaction in the fuel processor, and may also be used in a combustor to generate heat and combustion exhaust. The combustion exhaust can be used to drive a turbine to generate power.

摘要: Several air inputs are typically required in removal of carbon monoxide from a fuel reformate, particularly when using the reformate in a PEM (polymer electrolyte membrane) fuel cell. Control can be greatly simplified by distributing the air or oxygen among the inlets in a fixed ratio using a fixed dimension flow path, such as sized orifices, conduits, and the like, and selecting the total oxygen input to the system based on the operating state of the system and its operating map.

摘要: A catalytic heat exchanger comprises a first channel and a second channel, separated by a partition wall. Catalyst coated metal substrates are removably inserted into the first or the second channel or both, which facilitates catalytic reactions in the channel. Energy released in the reaction in one channel is transferred through the partition wall to heat the fluid in the other channel. The catalytic heat exchangers can be used in a fuel processing system to convert hydrocarbon fuels to a hydrogen rich reformate.
