Role of Heat Transfer in Molten Carbonate Fuel Cell Performance
Abstract
The heat and mass transfer schemes used in the numerical modeling of large, nonisothermal molten carbonate fuel cell stacks are described. The model is used to compute detailed spatial distributions of temperature, current density, reactant utilizations and compositions, and voltage losses in addition to average thermal and electrical performance characteristics. The numerical solution procedure which partially decouples the heat transfer and mass transfer equations is outlined. A number of computed cell temperature and current density distributions are presented to illustrate the effects of cell structural parameters, operating conditions, and flow geometry on cell temperature and current density distributions. Some effects of internal methane reforming are also highlighted. 14 refs.
