  1. 1. Computational Analysis of Gas Flow and Heat Transport Phenomena in Ducts Relevant for Fuel Cells

    Författare :Jinliang Yuan; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik; PEMFC.; SOFC; CFD; Duct; Transport Process; Fuel Cell; Heat Transfer; Gas Flow; Numerical Simulation; Analysis;

    Sammanfattning : The thesis concerns modeling, simulation and numerical analysis of heat and mass transport, and fluid flow in ducts of both solid oxide fuel cells (SOFCs) and proton exchange membrane fuel cells (PEMFCs). The unique fuel cell boundary conditions (thermal, mass) for the flow ducts in fuel cells are identified and applied. LÄS MER

  3. 2. Numerical simulation of multi-scale transport processes and reactions in pem fuel cells using two-phase models

    Författare :Munir Khan; Jinliang Yuan; Bengt Sundén; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; numerical analysis; multi-scale; multi-phase; reacting flows; multi-component;

    Sammanfattning : A numerical study for the cathode of a PEM fuel cell has been performed in this study. The results have been limited to cathode only because, in PEM fuel cells, the oxygen reduction reactions, ORRs, are considered the rate limiting reactions and govern the fuel cell performance. LÄS MER
