“…As an energy carrier, hydrogen can be used to produce electrical power in a fuel cell. The use of fuel cells is attractive for the vehicle industry due to their high energy conversion efficiency and low emissions [2]. However, refueling of hydrogen is a major obstacle for the deployment of fuel cell vehicles owing to the lack of infrastructure [3].…”

Abstract:Methanol steam reforming is a promising technology for producing hydrogen for onboard fuel cell applications. The methanol conversion rate and the contents of hydrogen, carbon monoxide and carbon dioxide in the reformate, significantly depend on the reforming catalyst. Copper-based catalysts and palladium-based catalysts can effectively convert methanol into hydrogen and carbon dioxide. Copper and palladium-based catalysts with different formulations and compositions have been thoroughly investigated in the literature. This work summarized the development of the two groups of catalysts for methanol steam reforming. Interactions between the activity components and the supports as well as the effects of different promoters were discussed. Compositional and morphological characteristics, along with the methanol steam reforming performances of different Cu/ZnO and Pd/ZnO catalysts promoted by Al 2 O 3 , CeO 2 , ZrO 2 or other metal oxides, were reviewed and compared. Moreover, the reaction mechanism of methanol steam reforming over the copper based and palladium based catalysts were discussed.

The fuel cell based auxiliary power unit (APU) is promising for power source of armed vehicles due to its silence and high efficiency. Especially, the on board hydrogen generation and fed to fuel cell system was core technology of this power system. In this study, we analyzed the performance of the Auto thermal reactor (ATR) that produce the hydrogen from the fuel, integrated High temperature polymer electrolyte fuel cell (HT-PEFC) by Aspen plus software. The fuel was designed as a n-dodecane for analysis of military fuel (JP-8).

“…The catalytic partial oxidation (CPOX) of liquid hydrocarbons over rhodium at short contact times is an efficient route to on-board syngas production for a fuel cell with the reformer and the fuel cell forming an auxiliary power unit [1][2][3][4][5][6]. Rh/Al 2 O 3 catalysts are the most efficient catalysts for a high syngas yield [7][8][9][10][11][12][13][14][15].…”

“…Nevertheless, a high syngas yield with low by-product formation and stable operation has been achieved for many different hydrocarbons and logistic fuels [1][2][3][4][5][24][25][26][27][28][29][30][31][32][33][34]. Still missing for sulfur-containing jet fuels are spatially-resolved concentration profiles, which are crucial for the understanding of the interplay between the main reactions and side reactions, e.g., cracking reactions, in dependence on the axial position.…”

Abstract:The catalytic partial oxidation (CPOX) of several hydrocarbon mixtures, containing n-dodecane (DD), 1,2,4-trimethylbenzene (TMB), and benzothiophene (BT) as a sulfur compound was studied over a Rh/Al 2 O 3 honeycomb catalyst. The in-situ sampling technique SpaciPro was used in this study to investigate the complex reaction system which consisted of total and partial oxidation, steam reforming, and the water gas shift reaction. The mixtures of 83 vol % DD, 17 vol % TMB with and without addition of the sulfur compound BT, as well as the pure hydrocarbons were studied at a molar C/O-ratio of 0.75. The spatially resolved concentration and temperature profiles inside a central channel of the catalyst revealed three reaction zones: an oxidation zone, an oxy-reforming zone, and a reforming zone. Hydrogen formation starts in the oxy-reforming zone, not directly at the catalyst inlet, contrary to methane CPOX on Rh. In the reforming zone, in which steam reforming is the predominant reaction, even small amounts of sulfur (10 mg S in 1 kg fuel) block active sites.
