Performance Improvement of WaveLike PEMFC Stack with Compound Membrane Electrode Assembly
The proton exchange membrane fuel cell (PEMFC) technology has drawn considerable attention during past two decades and has potential for automotive applications due to high energy density and low impact on environments [1, 2]. Nevertheless, commercialization of fuel cell vehicles still depends on achieving higher volumetric power density and specific power in order to compete with traditionally...
متن کاملEffect of Deflected Membrane Electrode Assembly on Species Distribution in PEMFC
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...
متن کاملA Novel Design of Wave-Like PEMFC Stack with Undulate MEAs and Perforated Bipolar Plates
Fuel cells are being pursued for a wide variety of applications due to their high theoretical efficiency and environmental friendliness [1, 2]. In particular, proton exchange membrane fuel cells (PEMFCs), because of the advantages of low temperature operation, fast start-up, system robustness and low emissions, are attractive for automotive and portable applications [3]. However, commercialisat...
متن کاملThe effect of vertical injection of reactants to the membrane electrode assembly on the performance of a PEM fuel cell
In order to present a new and high performance structure of PEM fuel cell and study the influence of the flow direction and distribution on the rate of reactants diffusion, three novel models of vertical reactant flow injection into the anode and cathode reaction area field have been introduced. They consist of one inlet and two inlets and also a continuous channel. The governing equations on t...
