Numerical Studies of Solid Oxide Fuel Cells
This paper describes a program of research aimed at improved mathematical models of fuel cells. Three distinct models were developed based on (a) a detailed numerical model of flow, heat and mass transfer (b) a flow-based distributed resistance approach, and (c) a presumed-flow method. Each of these methods has merits and drawbacks. The models were used to investigate the temperature variations in a fuel cell stack under typical operating conditions. The models and results obtained are discussed in detail.
