  5. 4. Modeling and Optimization of a Fuel Cell Hybrid System

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Lorenzo Bertini; [2011]
    Nyckelord :Series hybrid; Simulink model; PEMFC; Supercapacitor; Spiros IV;

    Sammanfattning : The purpose of this project was the modeling, optimization and prediction of a hybrid system composed of a fuel cell, a dc-dc converter and a supercapacitor in series. Lab tests were performed for each device to understand their behavior, and then each one was modeled using software (Simulink). LÄS MER
