1	Thermal energy management and chemical reaction investigation of micro-proton exchange membrane fuel cell and fuel cell system using finite element modelling McGee, Seán January 2015 (has links) Fuel cell systems are becoming more commonplace as a power generation method and are being researched, developed, and explored for commercial use, including portable fuel cells that appear in laptops, phones, and of course, chargers. This thesis examines a model constructed on inspiration from the myFC PowerTrekk, a portable fuel cell charger, using COMSOL Multiphysics, a finite element analysis software. As an educational tool and in the form of zero-dimensional, two-dimensional, and three-dimensional models, an investigation was completed into the geometric construction, air conditions and compositions, and product materials with a best case scenario completed that summarizes the results identified. On the basis of the results of this research, it can be concluded that polyoximetylen and high-density polyethylene were considered as possible materials for the majority of the product, though a more thorough investigation is needed. Air flow of above 10 m/s, air water vapour mass fraction below 50% and initial temperature between 308K and 298K was considered in this best scenario. Suggestions on future expansions to this project are also given in the conclusion. 0D model 2D model 3D model chemical engineering Comsol Multiphysics energy environment FC fluid dynamics fuel cell systems heat transfer JAQ laboratory experiments mobile charging modeling modelling myFC PEM polymer electrolyte membrane PowerTrekk process engineering proton exchange membrane sustainability 0D-Modell 2D-Modell 3D-Modell Chemieingenieurwesen COMSOL Multiphysics Energie Umwelt FC Fluiddynamik Brennstoffzellensysteme Wärmeübertragung JAQ Laborexperimente mobile Ladesysteme Modellieren myFC PEM Feststoffpolymer-Brennstoffzelle PowerTrekk Verfahrenstechnik Protonenaustauschmembran-Brennstoffzelle Nachhaltigkeit 0D-modell 2D-modell 3D-modell kemiteknik Comsol Multiphysics energi miljö FC fluiddynamik bränslecellssystem värmeöverföring JAQ laboratorieförsök mobil laddning modellering myFC PEM polymerelektrolytmembran PowerTrekk processteknik protonväxlingsmembran hållbarhet Chemical Engineering Kemiteknik
