Title: An advanced fuel cell simulator
Author: Acharya, Prabha Ramchandra
Abstract: Fuel cell power generation systems provide a clean alternative to the conventional fossil fuel based systems . Fuel cell systems have a high e & #64259 ;ciency and use easily available hydrocarbons like methane . Moreover , since the by -product is water , they have a very low environmental impact . The fuel cell system consists of several subsystems requiring a lot of e & #64256 ;ort from engineers in diverse areas . Fuel cell simulators can provide a convenient and economic alternative for testing the electrical subsystems such as converters and inverters . This thesis proposes a low -cost and an easy -to -use fuel cell simulator using a programmable DC supply along with a control module written in LabVIEW . This simulator reproduces the electrical characteristics of a 5kW solid oxide fuel cell (SOFC ) stack under various operating conditions . The experimental results indicate that the proposed simulator closely matches the voltage -current characteristic of the SOFC system under varying load conditions . E & #64256 ;ects of non -electrical parameters like hydrogen & #64258 ;ow rate are also modeled and these parameters are taken as dynamic inputs from the user . The simulator is customizable through a graphical user interface and allows the user to model other types of fuel cells with the respective voltage -current data . The simulator provides an inexpensive and accurate representation of a solid oxide fuel cell under steady state and transient conditions and can replace an actual fuel cell during testing of power conditioning equipment .
