Effective Distribution

Proton exchange membrane fuel cell (PEMFC) system is an advanced power system for the future that is sustainable, clean and environmental friendly. The flow channels present in bipolar plates of a PEMFC are responsible for the effective distribution of the reactant gases. Uneven distribution of the reactants can cause variations in current density, temperature, and water content over the area of a PEMFC, thus reducing the performance of PEMFC. By using Serpentine flow field channel, the performance is increased. Two types of serpentine flow field channels are implemented such as curved serpentine flow field channel and normal serpentine flow field channels. The result shows that curved serpentine flow field channel gives better current density and power density, thus increasing the performance of PEMFC.

The geometrical and flow parameters are governing the performance of the Proton Exchange Membrane Fuel Cell (PEMFC). The flow channels are used for distributing the reactants uniformly throughout the active area of fuel cell. Among different flow field designs, the serpentine flow field can give better performance to the PEM fuel cell. This paper numerically investigates the effects of the serpentine flow field with different number of passes. The 2 pass, 3 pass and 4 pass serpentine flow field designs of same rib size and channel size were modelled and analyzed using commercially available software package. From the polarization curves and performance curves drawn using the numerical results, the performance of three flow channel designs were compared and the maximum power densities of each design were found

Flow Field Design

As fossil fuels are becoming less reliable and more costly, the Proton Exchange Membrane Fuel Cell (PEMFC) is emerging as the primary candidate to replace the stationary and transport applications. In this study numerical simulation on PEMFC is done by commercially available Computational Fluid Dynamics (CFD) software. A three-dimensional, model of a single PEM Fuel cell with serpentine flow field design has been used for the study. The numerical model is 3-D steady, incompressible, single phase and isothermal includes the governing of mass, momentum, energy, and species along with electrochemical equations. All of these equations are simultaneously solved in order to get current flux density and H2, O2and H2O fractions along the flow field design.

This study developed an eight-segmented fuel cell for investigating local current distribution and stability along channel with six-pass serpentine flow field. The stoichiometry of anode was 1.2 and cathode was 4 as the benchmark for comparison. When the stoichiometry flow rate of cathode was 4 and anode decreased to 1.05, which caused the hydrogen starvation on the downstream. The decrease of cathode stoichiometry from 4 to 2 resulted in less water diffusing to membrane and slight decrease of the conductivity on the gas-inlet segment. The cathode stoichiometry of 1.2 showed better performance than the stoichiometry of 2 at 8th segment. The reason is the hydration of membrane by water produced. When the fuel cell was operating under full humidity at 0.5V constant voltage, the current density would oscillate with time at different cathode stoichiometry. This result indicated that the location causes channel water flooding and draining alternately. The oscillation decreased at lower cathode stoichiometry.
