Numerical Modeling of the Influence of Gas Diffusion Layer Properties on Liquid Water Transport and Transient Responses in a Proton Exchange Membrane Fuel Cell
In this study, a one-dimensional, two-phase transient model has been developed to study the transient behavior of water transport in the porous gas diffusion layer (GDL) of a proton exchange membrane fuel cell PEM fuel cell. This model based on the numerical resolution of the mass transport of liquid water and oxygen in the porous GDL is used to gauge the effects of various design and operational parameters, namely, the current density, GDL thickness and GDL permeability, on the overall performance of the system.
期刊介绍：
Microgravity Science and Technology – An International Journal for Microgravity and Space Exploration Related Research is a is a peer-reviewed scientific journal concerned with all topics, experimental as well as theoretical, related to research carried out under conditions of altered gravity.
Microgravity Science and Technology publishes papers dealing with studies performed on and prepared for platforms that provide real microgravity conditions (such as drop towers, parabolic flights, sounding rockets, reentry capsules and orbiting platforms), and on ground-based facilities aiming to simulate microgravity conditions on earth (such as levitrons, clinostats, random positioning machines, bed rest facilities, and micro-scale or neutral buoyancy facilities) or providing artificial gravity conditions (such as centrifuges).
Data from preparatory tests, hardware and instrumentation developments, lessons learnt as well as theoretical gravity-related considerations are welcome. Included science disciplines with gravity-related topics are:
− materials science
− fluid mechanics
− process engineering
− physics
− chemistry
− heat and mass transfer
− gravitational biology
− radiation biology
− exobiology and astrobiology
− human physiology
