This article presents the results of a numerical study, using computational fluid dynamics (CFD) analysis to investigate the species distribution of proton exchange membrane fuel cells (PEMFCs) with deflected membrane electrode assembly (MEA). These new geometry were examined while employing three-dimensional, single phase, non-isothermal and parallel flow for model of a PEM fuel cell. This num...

Particle image velocimetry was used to measure 2D velocity fields in representative regions of interest within flow channels of interdigitated and single-serpentine proton exchange membrane (PEM) fuel cell models. The model dimensions, gas diffusion layer (GDL) permeability, working fluid, and flow rates were selected to be geometrically and dynamically similar to the cathode-side airflow in a ...

Proton exchange membranes (PEMs) play an important role in the fuel cell systems. A good PEM must meet a series of requirements such as high proton conductivity, excellent mechanical strength and stability, chemical and electrochemical stability, low fuel crossover, etc. Nafion is currently the most commercially utilized electrolyte membranes for polymer electrolyte fuel cells, with high chemic...

Abstract In recent years, proton exchange membrane (PEM) fuel cells have regained worldwide attention from academia, industries, investors, and governments. The prospect of PEM has turned into reality, with cell vehicles successfully launched in the market. However, today’s remain less competitive than combustion engines batteries, primarily due to their high cost short lifetime, which are sign...

Fuel cell technologies have several applications in stationary power production, such as units for primary generation, grid stabilization, systems adopted to generate backup power, and combined-heat-and-power configurations (CHP). The main sectors where fuel cells been employed are (a) micro-CHP, (b) large applications, (c) UPS, IPS. size is strongly related the needed from load. Since this sec...

The adoption of fuel cells (FCs) for industrial applications, transportations and home power generation is widely increased during recent years. Because FCs are still in the development stage, to evaluate and validate fuel cell technologies suitable test systems are needed. In a fuel cell both chemical and electric sections can be founded, so to control its behaviour the measurement of differen...

An essential requirement for an operating PEM fuel cell is providing proper water content in the membrane. To avoid water flooding an appropriate water balance is required. Here, an analytic model of a planar membrane humidifier for PEM fuel cell is proposed where the effect of dimensional parameters includes membrane thickness, membrane area and channel hydraulic diameter are investigated. A N...
