  1. 1. A NUMERICAL MODEL OF HEAT- AND MASS TRANSFER IN POLYMER ELECTROLYTE FUEL CELLS : A two-dimensional 1+1D approach to solve the steady-state temperature- and mass- distributions

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens högskola/Framtidens energi

    Författare :Emil Skoglund; [2021]
    Nyckelord :PEFC; PEM; convection; mass transport; heat transport; co-flow; temperature profile; heat transfer model; transient; steady state; water concentration profile; water vapor profile; relative humidity; through-plane cross section;

    Sammanfattning : Methods of solving the steady state characteristics of a node matrix equation system over a polymer electrolyte fuel cell (PEFC) were evaluated. The most suitable method, referred to as the semi-implicit method, was set up in a MATLAB program. LÄS MER

  3. 2. Finite Element Method for 1D Transient Convective Heat Transfer Problems

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för matematik (MA)

    Författare :Whokko Schirén; [2018]
    Nyckelord :Advection-Diffusion; Convection; Convection Problems; Finite Element Method; FEM; Transient 1D Heat Equation; Discretisation;

    Sammanfattning : We study heat transfer in one dimension with and without convection, also called advection-diffusion. This is done using the Finite Element Method (FEM) to discretise the mathematical model, i.e. the heat equation. LÄS MER

  4. 3. Dynamic modeling of a solid oxide fuel cell system in Modelica

    Magister-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Daniel Andersson; Erik Åberg; [2010]
    Nyckelord :Solid oxide fuel cell Modelica simulation; Technology and Engineering;

    Sammanfattning : In this study a dynamic model of a solid oxide fuel cell system has been developed. The work has been conducted in cooperation with Modelon AB using the Modelica language and the Dymola modeling and simulation tool. Modelica is an equation based, object oriented modeling language, which promotes flexibility and reuse of code. LÄS MER
