“…In another work, Kivisaari et al (2001) compared the application of three process flowsheeting packages, Design-II, Aspen Plus and Spence, for fuel cell system simulation. They found that, in spite of good agreement of the overall results, significant differences between the packages became apparent on more detailed examination.…”

A solid oxide fuel cell (SOFC) system consists of a fuel cell stack with its auxiliary components. Modelling an entire SOFC system can be simplified by employing standard process flowsheeting software. However, no in-built SOFC module exists within any of the commercial flowsheet simulators. In Amiri et al. (Comput. Chem. Eng., 2015, 78:10-23), a rigorous SOFC module was developed to fill this gap. That work outlined a multi-scale approach to SOFC modelling and presented analyses at compartment, channel and cell scales. The current work extends the approach to stack and system scales. Two case studies were conducted on a simulated multilayer, planar SOFC stack with its balance of plant (BoP) components. Firstly, the effect of flow maldistribution in the stack manifold on the SOFC's internal variables was examined. Secondly, the interaction between the stack and the BoP was investigated through the effect of recycling depleted fuel. The results showed that anode gas recycling could be used for managing the gradients within the stack, while also improving fuel utilisation and water management.

“…Process simulation software has been widely used for evaluating fuel cell systems performance [16][17][18]. In this work, a commercial simulator was used to solve the mass and energy balances, and to compute the operating conditions for the process units.…”

“…Since fuel cells are an innovative device, a numerical code to simulate its behaviour must be implemented using a proprietary model. Previous work can be found in the literature [4,10,11], where fuel cell stacks are inserted in a whole power plant, but very often the fuel cell block is zero-dimensional, i.e., its performance is not affected by operating plant parameters, such as fuel composition, fuel utilization, current density, etc. For this reason, the authors, have developed a module to be integrated into the commercial software for plants simulation Aspen Plus.…”

“…Moreover, very often these models do not take very important phenomena that occur in a fuel cell and that are observable only through experience into account. The Industrial Plants Group of the University of Perugia, in collaboration with ENEA (Ente per le Nuove Tecnologie Energia ed Ambiente), Ansaldo Fuel Cells and CNR (Consiglio Nazionale delle Ricerche) has created a Molten Carbonate Fuel Cell test rig [10]. The model results were compared with experimental data, recognizing, during the model development phase itself, which hypotheses had to be removed and which could be considered acceptable.…”

The necessity of a simulation tool for integrated power plant with MCFCs has led to the development of a numerical model by which it is possible to evaluate the performances of the cell and the plant the cell is embedded in. Many mathematic models can be found in the literature that evaluate electrochemical fuel cell performance [1–9]; however the model must be developed according to a specific target. In other words, if the main purpose of the study is, for example, shape optimization, the model must be very accurate concerning internal conditions, such as current density, temperature distribution, etc. The models found in the literature [1–3, 5, 9] seem to produce excellent results. However, the aim here is to create a mathematical model for fuel cell stacks, which can be integrated into a simulation modular code for the Balance of the Plant (BoP) optimization. Plant modelling can be performed using commercially available software. Often, since fuel cells are innovative devices, numerical codes that simulate their behaviour must be implemented by using a proprietary code. Previous papers can be found in the literature [4, 10, 11], where fuel cell stacks are inserted in an entire power plant, but very often the fuel cell block is zero‐dimensional and it is not affected by the variation in input parameters. The authors, for this purpose, have developed a module to be integrated into commercial software for plants simulation, Aspen Plus. The model adopted is simple, but at the same time, it calculates with good accuracy fuel cell performance under any conditions. Another important element taken into account during the code development is the validation through experimental data. In the present work, the authors have adopted an analytic model for evaluating the electrochemical performance [6] of a fuel cell and results obtained are compared with those found out during the tests on a Molten Carbonate Fuel Cell. Some phenomena not described in the original model are considered and an enhanced model for the cell performance is developed. The model obtained is therefore used to analyse fuel cell behaviour under several operating conditions. These results seem to fit very well with experimental analyses conducted in the test rig of the University of Perugia.
