“…A plot of products calculated from (30), assuming no inlet N 2 and H 2 O, is shown in Figure 7, which matches with the theoretical results in [29]. The mass flow rate of each species leaving the (19) can now be expanded. The enthalpy of the gas flow depends on the flow rate, the flow temperature, and the gas composition.…”

“…Since more heat is released from TOX reaction, operating CPOX at high λ O2C will overheat the CPOX and can permanently damage the catalyst bed. The desired value of λ O2C in the literature varies from 0.4 to 0.6 [8], [19], [22]. In this study, the desired value is chosen at λ O2C = 0.6 in order to allow some buffer for λ O2C before it becomes lower than 1 2 during transient deviations.…”

A control-oriented dynamic model of a catalytic partial oxidation-based fuel processor is developed using physicsbased principles. The Fuel Processor System (FPS) converts a hydrocarbon fuel to a hydrogen (H 2 ) rich mixture that is directly feed to the Proton Exchange Membrane Fuel Cell Stack (PEM-FCS). Cost and performance requirements of the total powerplant typically lead to highly integrated designs and stringent control objectives. Physics based component models are extremely useful in understanding the system level interactions, implications on system performance and in model-based controller design. The model can be used in a multivariable analysis to determine characteristics of the system that might limit performance of a controller or a control design.In this paper, control theoretic tools such as the relative gain array (RGA) and the observability gramian are employed to guide the control design for a FPS combined with a PEM-FC. For example this simple multivariable analysis suggests that a decrease in HDS volume is critical for the hydrogen starvation control. Moreover, RGA analysis shows different level of coupling between the system dynamics at different power levels. Finally, the observability analysis can help in assessing the relative cost-benefit ratio in adding extra sensors in the system.

“…It has also been reported that ceria-doped catalysts decrease carbon deposition during the POM reaction [14,15] and it was speculated that this is the result of their high oxygen ion mobility [16]. The importance of ceria-based materials in redox reactions has also been recognized due to their oxygen storage capacity and high ionic conductivity.…”

Hydrogen (H2) is currently used mainly in the chemical industry for the production of ammonia and methanol. Nevertheless, in the near future, hydrogen is expected to become a significant fuel that will largely contribute to the quality of atmospheric air. Hydrogen as a chemical element (H) is the most widespread one on the earth and as molecular dihydrogen (H2) can be obtained from a number of sources both renewable and nonrenewable by various processes. Hydrogen global production has so far been dominated by fossil fuels, with the most significant contemporary technologies being the steam reforming of hydrocarbons (e.g., natural gas). Pure hydrogen is also produced by electrolysis of water, an energy demanding process. This work reviews the current technologies used for hydrogen (H2) production from both fossil and renewable biomass resources, including reforming (steam, partial oxidation, autothermal, plasma, and aqueous phase) and pyrolysis. In addition, other methods for generating hydrogen (e.g., electrolysis of water) and purification methods, such as desulfurization and water-gas shift reactions are discussed.
