“…This is the effect of exponential increasing of ohmic and activation resistances. These results are in good agreement with the results of the previous researchers [22,29,30]. In the meantime, the power output is initially increased with increasing the current density and then dropping down at high current density (Fig.…”

Abstract. In this work, integrative biomass gasification with solid oxide fuel cell (SOFC) system using rice husk as feedstock was studied under various operations. It was found that the stand-alone mixed air-steam gasification provided significant higher benefit than alone air and steam gasification. The mathematical model was developed to predict the electrical, thermal and overall efficiency of the system. It was found that the SOFC with steam gasification also provided the greatest overall efficiency of 96%. Hence, the steam gasification is a promising option for coupling with SOFC to generate electricity from biomass.

“…Voltage loss calculations are calculated based on the ideal cell voltage as the potential redution by ohmic, activation, and concentration losses [22][23][24]. Theoretically, the ohmic loss is related to the limitation of electrical conductivity of fuel cell stack materials.…”

“…The authors may be able to use the word novel, but should not claim that their system is unique. Not only have many companies developed SOFC systems that contain a steam reformer that is heat-integrated with solid oxide fuel cells, but many previous publications have analyzed such systems (see, for example [2][3][4][5][6][7][8][9]). The addition of carbon separation downstream from such a system does not make it unique either.…”

“…Characteristics and arrangement of these modules are based on information extracted from data published in [25,[29][30][31], which are related to the previously cited Methapu project [15]. The system main dimensions have been defined taking as a basis data provided in [27,29,32].…”

“…The result, as has been mentioned, will be electricity, but the surplus hydrogen is partially re-used and partially burned off in the catalytic burner to assist the reforming process in the FP and to prevent an atmosphere containing an excess of hydrogen, as it is an inflammable gas. Taking as a basis the conceptual design of a 250 kW SOFC system described in [29] fed by natural gas, it has been assumed that the system will be housed in an ISO standard container with the dimensions 5.8 m Â 2.3 m Â 2.3 m, being 12,350 kg the estimated weight. It has been assumed also that the system includes the elements listed in Table 2 and is divided into three temperature zones, clearly differentiated in Fig.…”

Conceptual design of PSV ship with hybrid diesel electric-FC power plant is presented. Two methanol-fed 250 kW SOFC systems are installed on board with 21 days autonomy. Cogeneration heat from SOFC allows answering hot water needs on board. Optimized hull design allows sailing with SOFCs and only one diesel generator. At ECO-Speed operation mode pollutant emissions are notably reduced. a b s t r a c tNowadays increasing fuel prices and upcoming pollutant emission regulations are becoming a growing concern for the shipping industry worldwide. While fuel prices will keep rising in future years, the new International Convention for the Prevention of Pollution from Ships (MARPOL) and Sulphur Emis-sions Control Areas (SECA) regulations will forbid ships to use heavy fuel oils at certain situations. To fulfil with these regulations, the next step in the marine shipping business will comprise the use of cleaner fuels on board as well as developing new propulsion concept. In this work a new conceptual marine pro-pulsion system is developed, based on the integration of diesel generators with fuel cells in a 2850 metric tonne of deadweight platform supply vessel. The efficiency of the two 250 kW methanol-fed Solid Oxide Fuel Cell (SOFC) system installed on board combined with the hydro dynamically optimized design of the hull of the ship will allow the ship to successfully operate at certain modes of operation while notably reduce the pollutant emissions to the atmosphere. Besides the cogeneration heat obtained from the fuel cell system will be used to answer different heating needs on board the vessel.
