A two-dimensional numerical model of a planar solid oxide fuel cell
A two-dimensional CFD model of a planar solid oxide fuel cell (SOFC) has been developed.This model can predict the performance of SOFC at various operating and design conditions.The effect of Knudsen diffusion is accounted in the porous electrode (backing) and reaction zonelayers. The mathematical model solves conservation of electrons and ions and conservation ofspecies. The model is formulate...
متن کاملSelf-contained Oxygen Supply for Self-regulating Miniature Fuel Cell
We report a microstructure, which if electrified in a hydrogen peroxide solution covers its top with a thin layer of oxygen gas in a self-regulating manner. In pursuit of realizing a full fuel cell with no moving part, we have successfully developed such an oxygen-generating surface and integrated it as a direct oxygen supply to the cathode of our previously developed miniature fuel cells. The ...
متن کاملA New Sensitivity Study of Thermal Stress Distribution for a Planar Solid Oxide Fuel Cell
Converting chemical energy into electricity is done by an electro-chemical device known as a fuel cell. Thermal stress is caused at high operating temperature between 700 oC to 1000 oC of SOFC. Thermal stress causes gas escape, structure variability, crack initiation, crack propagation, and cease operation of the SOFC before its lifetime. The aim of this study is to presen...
متن کاملAn octane-fueled solid oxide fuel cell.
There are substantial barriers to the introduction of hydrogen fuel cells for transportation, including the high cost of fuel-cell systems, the current lack of a hydrogen infrastructure, and the relatively low fuel efficiency when using hydrogen produced from hydrocarbons. Here, we describe a solid oxide fuel cell that combines a catalyst layer with a conventional anode, allowing internal refor...
متن کاملIntegrating Multiple Solid Oxide Fuel Cell Modules
Abstract-According to SECA program guidelines, solid oxide fuel cells (SOFC) will be produced in the form of 3–10 kW modules for residential use. In addition to residential use, these modules can also be used in apartment buildings, hospitals, etc., where a higher power rating would be required. For example, a hospital might require a 250 kW power supply. To provide this power using the SOFC mo...
