Modeling Study of High Fuel Utilization in Solid Oxide Fuel Cell.
Masters thesis, Indian Institute of Technology Hyderabad.
Abstract
Solid Oxide Fuel Cell offers higher conversion efficiency compared to all other fuel cells. Fuel cell technology is also a cleaner alternative where particulate and NOx emissions can be essentially eliminated and the carbon emissions per unit of electrical energy are much lower. This work aims to use simulations from a detailed coupled multiphysics model to identify and evaluate desirable operating regions for a SOFC. We are interested in maximizing fuel utilization, cell efficiency as well as power density without going into operating regions where degradation modes such as Ni oxidation become active. In this study, we present a series of parametric studies by simulating the model at different flow-rates, fuel compositions, temperatures and cell voltages.
