Abstract

The investigation conducted is aimed at establishing the best operational conditions to obtain the best output of a 5-cell stack Proton Exchange Membrane fuel cell (PEMFC) with three different bipolar plate geometries. The work further explores the best input parameters that will yield the maximum voltage, current power as well as fuel efficiency from each of the three designs under investigation. A polarization curve was generated for each of the three designs and a surface response plot developed for each experiment. The work concluded that the spiral design performed very well compared to the other designs under investigation and even existing on the fuel cell market.

Key findings

  • The spiral design performed better than the other two designs in terms of voltage, current power, and fuel efficiency.
  • A polarization curve was generated for each design, and a surface response plot was developed for each experiment.
  • The spiral design outperformed existing designs on the fuel cell market.
