..., and they are modeled with transient energy equations and dynamic molar balance equations. In addition, both reaction enthalpy and convection heat transfer between the catalyst-coated fins and fuel-steam mixture channels are considered. Several parametric simulations are performed as methane steam as a primary fuel...

... in the 1–2 kW range to enable a better understanding of how component heat loss affects process gas temperature and flow requirements throughout the flowsheet. The thermal performance of the system is examined for various thermal management strategies that involve altering the convective and radiative heat...

.... Isothermal and adiabatic walls are chosen as the different boundary conditions in order to simulate the real situation, which lies somewhere in between. In the situation where adiabatic walls are assumed, the result shows that heat convection dominates the heat transfer process. However, heat conduction...

...Y. N. Magar; R. M. Manglik Convective heat and mass transfer in a planar, trilayer, solid oxide fuel cell (SOFC) module is considered for a uniform supply of volatile species ( 80 % H 2 + 20 % H 2 O vapor) and oxidant ( 20 % O 2 + 80 % N 2 ) to the electrolyte surface with a uniform electrochemical...

... through the porous medium. Such convective bypass can enhance fuel cell performance by supplying fresh reactant to the lands regions and also by driving out product water from under the lands to the flow channels. 13 02 2006 05 06 2006 proton exchange membrane fuel cells velocimeters...

... their porous structures. The multi-component convective-diffusive flows are simulated using a new theory of flow in porous material, the cylindrical pore interpolation model. The effects of the catalyzed methane reforming and water-gas shift chemical reactions are also considered using appropriate kinetic...

... at the anode in high concentrations. This paper presents a simple thermal transport model for analyzing heat transfer and improving thermal management within planar SOFCs. The model was implemented using a commercial computational fluid dynamic code and includes conduction, convection, and radiation...
