...; and (4) at low cell voltage, current density distribution in the catalyst layer shows stronger nonlinearity in the anode than in the cathode. alkaline direct ethanol fuel cell permselective membrane-free simulation With the advancement of material and electrochemical engineering, alkaline...

... on the impact of different bend angle and width of serpentine flow channels and tests how they improve the performance. Three-dimensional simulations are carried out with a steady, two-phase, multicomponent and electrochemical model, using CFD-ACE+, the commercial CFD code. Through simulation with various bend...

... in order to provide realistic temperature profiles to the finite-element analysis of the ceramic SOFC membrane-electrode assembly (MEA). The resulting simulation tool is employed for three different analyses: In the first analysis, temperature profiles provided by the thermo-electrochemical model are used...

... is carbon formation within the ceramic layers at intermediate temperatures. This paper proposes a model solution using the CFD-ACE software package to simulate the behavior of a tubular SOFC. A detailed thermodynamic analysis is carried out to predict the boundary of carbon formation for SOFCs fueled...

... into account the strong point-to-point anode and cathode reaction coupling due to gas crossflow. Simulations (carried out after suitable thermodynamical and electrochemical parameter tuning) highlight, for instance, the presence of dynamics, linked to the electrochemical behavior, with time constants...

.... In particular, in order to understand the impact of concentration losses on the performance of composite electrodes, the simulations have been run with two models, one including and the other one neglecting the mass transport equations. The results show that concentration losses play a role only with thick...

... developed tubular model. In this paper, a three dimensional numerical model to simulate the steady state heat transfer and fluid flow of a flat-tube HPD–SOFC is developed. A computer code is programmed using the FORTRAN language to solve the governing equations for continuity, momentum, and energy...
