Proton Exchange Membrane Fuel Cell (PEMFC) is a device that generates electricity through an electrochemical reaction of oxygen air and hydrogen fuel. Thetransportofoxidantand fuel through the bipolarplatesis a significant factor affecting the cell performance. Currently, present work concentrates highly on flow field layout and channels design configurations. In this paper, the development two flow field layouts are discussed with different inlet/outlet channel ratio. Serpentine-paralleldesignisusedasthe base layout. The flow fields have inlet/outlet channel ratio of 1:1 and multiple inlet 2:1 configurations. Graphite is used as theplate material.Theanodeflowchannelis 2 mmx 1.2 mmx 2 mm meanwhile the cathode channel is 2 mm x 0.5 mm x 2 mm fora xbxwrespectively.Theactiveareais 25 cm2 with 5 cmx 5 cm dimensions. The fields were fabricated by Roland EGX-360 Desktop Engraver machine that involved drilling and profiling process. The fuel cell assembly process is explained in detail. The gasketmaterialis made from two materials which are Polyimide and Silicon. A series of pre-conditioning experiments were carried out in both fuel cells for confident purposes.

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.

In this paper, the influence of the optimization for flow field size on the proton exchange membrane fuel cell (PEMFC) performance under the inadequate air supply of cathode was studied based on the three-dimensional, steady-state, and constant temperature PEMFC monomer model. Additionally, the effect of the optimization for hybrid factors, including length, width, depth and width-depth, on the PEMFC performance was also investigated. The results showed that the optimization of the flow field size can improve the performance of the PEMFC and ensure that it is close to the level under the normal gas supply.
