Abstract

This study develops a unique three-dimensional computational fluid dynamic electrochemical model for open pore cellular foam material as a flow plate, comparing it to a double channel flow plate and experimental results, researching its application as an alternative to conventional flow plate materials in proton exchange membrane fuel cells. Using the same membrane electrode assembly and operating parameters, the model simulations, including hydrogen and oxygen distribution and water activity, are examined. IV-curves obtained from the model and experimentally, are analysed and the results are discussed. The model is validated by comparing simulated IV-curve results against experimental results, and model limitations are identified.
The results indicate that the open pore cellular foam material flow plate distributes both hydrogen and oxygen more evenly from inlet to outlet through the fuel cell, when compared to the double channel fuel cell, outperforming it in both simulated and experimental runs.
