Fuel cells are a growing new technology that can be applied in order to harness electrical energy out of hydrogen and hydrated air. When testing these devices however, pressure drops along the apparatus are strongly discouraged due to the fluctuation in gas volumetric flow rate that they incur. The design of the flow channels is critical to the fuel cell performance and water management. In this research, computational fluid dynamics (CFD) is used to analyze the gas manifold and a column channel inside of a fuel cell. The effect of the flow channel parameters on the flow rate and pressure drops are investigated to provide useful information to optimize the design of flow channels.
