“…Vollmar et al performed thermodynamic design calculations examining different operating modes of a solid oxide fuel cell (SOFC) hydrogen coproduction system and different overall system configurations, e.g., some included a proton exchange membrane fuel cell that would operate on the coproduced hydrogen [2]. They showed that high efficiencies could be achieved in a solid oxide fuel cell coproduction system [2].…”

h i g h l i g h t sA dynamic internal reforming-solid oxide fuel cell system model is developed. Electricity and hydrogen coproduction to meet dynamic building demand is modeled. The co-producing system well follows the measured building electric load dynamics. Dynamic operation of an SOFC system for co-producing hydrogen is demonstrated. Thermal and tank filling responses to dynamic operation are presented. a r t i c l e i n f o a b s t r a c tA dynamic internal reforming-solid oxide fuel cell system model is developed and used to simulate the coproduction of electricity and hydrogen while meeting the measured dynamic load of a typical southern California commercial building. The simulated direct internal reforming-solid oxide fuel cell (DIR-SOFC) system is controlled to become an electrical load following device that well follows the measured building load data (3-s resolution). The feasibility of the DIR-SOFC system to meet the dynamic building demand while co-producing hydrogen is demonstrated. The resulting thermal responses of the system to the electrical load dynamics as well as those dynamics associated with the filling of a hydrogen collection tank are investigated. The DIR-SOFC system model also allows for resolution of the fuel cell species and temperature distributions during these dynamics since thermal gradients are a concern for DIR-SOFC.

“…SOFC-based hybrid power plants have been proposed by researchers in extensive studies on integration of SOFCs in gas turbine (GT) and steam turbine (ST) power plants [3][4][5], along with a few on SOFC-Stirling hybrid systems [6,7], whereas studies on prospects of combining SOFC with a Polymer Electrolyte Fuel Cell (PEFC) are relatively limited [8][9][10][11]. Although, SOFC-GT and SOFC-ST power plants display high efficiencies when compared to conventional combined cycles, their operations are limited to large-scale plants only.…”

A hybrid fuel cell system (~10 kWe) for an average family house including heating is proposed. The investigated system comprises a Solid Oxide Fuel Cell (SOFC) on top of a Polymer Electrolyte Fuel Cell (PEFC). Hydrogen produced from the off-gases of the SOFC can be fed directly to the PEFC. Simulations for the proposed system were conducted using different fuels. Here, results for natural gas (NG), dimethyl ether (DME) and ethanol as a fuel are presented and analysed. Behaviour of the proposed system is further investigated by comparing the effects of key factors such as utilisation factor, operating conditions, oxygen-to-carbon (O/C) ratios and fuel preheating effects on these fuels. The combined system improves the overall electrical conversion efficiency compared with standalone PEFC or SOFC systems. For the combined SOFC and PEFC system, the overall power production was increased by 8%-16% and the system efficiency with one of the fuels is found to be 12% higher than that of the standalone SOFC system.
