The purpose of present study is to investigate the dynamic response of two conventional types of solid oxide fuel cells to the inlet air mass flow rate variation. A dynamic compartmental model based on CFD principles is developed for two typical planar and tubular SOFC designs. The model accounts for transport processes (heat and mass transfer), diffusion processes, electrochemical processes, a...

Abstract In metal–air batteries, the integrated solid‐state cathode is considered a promising design because it can solve problem of high interfacial resistance conventional cathodes. However, solid discharge products cannot be efficiently decomposed in an cathode, resulting batteries that are unable to operate for long periods time. Herein, (Gel‐Tempo cathode) sodium–air (SABs) capable promoti...

The luminosity of a zlOPo source has been detected using a photomultiplier technique. It is also found that photons are produced in air, glass and quartz when these materials are irradiated by a-particles. It is shown that the ' scintillations ' observed by Richards and Cole probably originated in these materials, and not in the various thin films to which they were ascribed. T is well known th...

The practical implementation of air-breathing microbial fuel cell (MFC) is critically linked to the development efficient materials as cathode and electrochemically active biofilm-based anode. In this contribution, we demonstrate feasibility by decorating a 3D carbon felt electrode with Pt nanoarrays (CF@Pt) bifunctional material garden compost bioanode cathode. Half-cell electrochemical charac...

In this paper, fault-tolerant MPC control of PEM fuel cells is addressed. MPC is a suitable control methodology to control fuel cell systems because of their multivariable and complex behaviour. Additionally, MPC is one of the control methodologies that can introduce more easily fault-tolerance. However, the problem of including actuator fault-tolerance in the control loops of these systems has...
