3D CFD modeling and experimental characterization of HT PEM fuel cells at different anode gas compositions

A numerical and experimental characterization of the performance of a High Temperature Polymer Electrolyte Membrane Fuel Cell (HT PEM FC) is presented. ng from the fluid dynamic optimization performed in a previous work, a detailed 3D CFD-electrochemical model of a single HT PEM FC is developed, in order to describe the internal fluid dynamic fields coupled to the electrochemical reactions. idate the numerical activity, an experimental campaign has been conducted on a single-cell prototype built ad-hoc, with both pure H2 and Syngas anodic feeding. sults of both the numerical and experimental investigations are compared to the performance of commercial HT PEM Fuel Cells, proving the good accuracy of our numerical method as well as the consistency of the experimental setup.
