Modeling the Effect of Discrete Distributions of Platinum Particles in the PEM Fuel Cell Catalyst Layer
In this study, the basic catalyst layer (CL) structure, consisting of carbon-supported Pt particles (C|Pt) and an ionomer binder, is investigated numerically by using COMSOL. The significance of modeling discrete Pt particles on the carbon support is highlighted by comparing the cell ... 詳細を見る
Irrotational Motion of an Incompressible Fluid Past a Wing Section in an Unbounded Region
Developers of numerical models who address the title problem face several hurdles, such as: (1), the need to formulate boundary conditions applicable in an unbounded region; (2), The need to specify conditions suitable to ensure a unique solution in a doubly connected region; and (3), ... 詳細を見る
Modeling the Behavior of a Polymer Electrolyte Membrane within a Fuel Cell Using COMSOL
One viable alternative to non-renewable fossil fuels is the fuel cell. A special class of FC i.e. Proton Exchange Membrane Fuel Cell (PEMFC) has been investigated during the present study. Membrane is a very important part of a PEMFC as most ohmic losses occurs here and limits the ... 詳細を見る
Multiphysics Modeling of Warm-Air Drying of Potatoes Slices
In this work we solve a model to simulate the drying of potatoes slices. The model considers both the transport of free and vapor water by applying a mechanistic approach. The critical moisture point (CMP) was considered, since it is a transition zone and it represents the point where ... 詳細を見る
