   Sammanfattning : This thesis presents numerical simulations of reacting transport phenomena in polymer electrolyte membrane (PEM) fuel cells. Broadly, the presented work is subdivided into macro and microscale simulations. 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
