Abstract

Energy need of the civilized world is ever increasing,
and as such, the subject of energy production from renewable energy sources is
gaining popularity in scientific studies. Amongst these studies are the researches
on fuel cell systems. In this study, the flow channels of the “proton exchange
membrane” (PEM) type fuel cell were designed, modelled, and studies were
conducted on three-dimensional channels of various designs via Comsol
Multiphysics simulation software, with hopes to contribute to the renewable
energy solutions. Proposed fuel cell designs and geometries of flow channels
were compared to existing fuel cells’ with exergetically efficient designs, in
terms of total exergy efficiency. Exergy efficiency analysis was conducted on
the membrane surfaces of the proposed flow channels. Anode and cathode side
exergy analyses, polarization curve of the system, voltage, current and produced
power parameter results were also inspected.
