“…The low purity which is shown by the presence of O-H functional group, may also become the reason of the low reforming result. In addition, biofuel gas should be mixed with water steam which should be input from another inlet in order to force gas reforming reaction and water gas shift as described in equation (1), (2) and (3) [19]. In this research, the resource of water steam only water molecules which were contained in the biofuel mixture.…”

“…In this research, the resource of water steam only water molecules which were contained in the biofuel mixture. Therefore, water molecules content might not be sufficient to reforme biofuel gas, ( 1 ) In general, it would be, C x H y + zH 2 O 2CO + ((y+2z)/2)H 2 ( 2 ) Meanwhile, the water gas shift follows equation (3) [19],…”

“…In general, methane can be synthesized, as a major product or a by-product, from many chemical processes, or even formation process [8]. In addition, methane in biogas can be directly fed to SOFC under dry conditions; however, there is a risk that is associated with contaminants in biogas when it is introduced to commercial SOFCs while using Ni-YSZ anode [9,10]. Therefore, either commercialized material development or fuel processing with cleaning technologies is required.…”

Design and Implementation of the Off-Line Robust Model Predictive Control for Solid Oxide Fuel Cells

An off-line robust linear model predictive control (MPC) using an ellipsoidal invariant set is synthesized based on an uncertain polytopic approach and then implemented to control the temperature and fuel in a direct internal reforming solid oxide fuel cell (SOFC). The state feedback control is derived by minimizing an upper bound on the worst-case performance cost. The simulation results indicate that the synthesized robust MPC algorithm can control and guarantee the stability of the SOFC; although there are uncertainties in some model parameters, it can keep both the temperature and fuel at their setpoints.

“…Solid oxide fuel cells (SOFCs) are able to convert hydrogen and/or carbon monoxide and oxygen-rich air [11,12] or biofuels produced by biomass gasification and anaerobic digestion [13,14] in electric energy with high conversion efficiency. Some research studies were conducted on innovative components' materials to reduce the SOFCs operating temperature [15][16][17][18][19][20].…”

Renewable sources and electric distribution network can produce or make available a surplus of electric and thermal energies. The Intermediate Temperature Solid Oxide Electrolyzer (IT-SOE) fed by CO2-steam mixtures can store these electric and thermal energies producing CO-H2 mixtures with high conversion efficiency. Inside the IT-SOE, the CO2-steam mixtures are converted into CO-H2 mixtures and O2 through cathodic and anodic electrochemical reactions and reverse water gas shift chemical reactions. In this article an IT-SOE stack fed by different types of steam mixtures was tested at different operating temperatures and the stack polarization and electric power curves were detected experimentally. At the highest hydrogen production operating temperature of the stack fed by steam mixtures, the experimental polarization and electric power curves of the stack fed by steam and CO2-steam mixtures were compared. A simulation model of the IT-SOE system (stack and furnace) fed by CO2-steam mixtures was formulated ad hoc and implemented in a MatLab environment and experimentally validated. At the highest hydrogen production stack operating temperature, the IT-SOE system thermal equilibrium current was evaluated through the simulation model. Moreover, the influence of this current on the IT-SOE system efficiency and the CO-H2 mixture degree of purity was highlighted.
